            Are you perhaps looking for df.drop_duplicates() ?

            With subset you can specify on which columns to operate, and with keep which rows to keep.

            How to properly code a scaled inverse Wishart prior for a MCMCglmm model?
            Asked 2021-Jun-12 at 01:25

            I am running a multivariate model (4 response variables) with two random effects using MCMCglmm(). I am currently using a inverse Wishart prior.

            ...

            ANSWER

            Answered 2021-Jun-12 at 01:25

            This is a two-part question:

            • what priors should I use for a multivariate random effect where the likelihood is concentrated at small values? (I am assuming that this is the reason you are looking for an alternative to the default inverse Wishart priors) [more suitable for CrossValidated]
            • which of these are available in MCMCglmm, and how do I implement them there? [good for Stack Overflow]

            The general trick is to decompose the covariance matrix into a multivariate component (the correlation matrix or inverse correlation matrix or something) and a vector of scaling parameters for the standard deviations (or inverse standard deviations); Lemoine suggests U(0,100) for the scaling priors, which I think is bad (why flat? I can't get to the precise page of Gelman and Hill 2007 where they discuss which distribution to use for scaling priors ... but I would be a little surprised if they actually recommended a uniform distribution on the variance scale ...)

            update having actually looked at your code (!): I think you're doing the right thing, except that nu=0.002 seems really extreme; see end for that discussion.

            This is basically what MCMCglmm does, but it uses a different (IMO better) choice for the scaling priors. It sounds scary:

            These priors are all from the non-central scaled F-distribution, which implies the prior for the standard deviation is a non-central folded scaled t-distribution (Gelman, 2006).

            but it boils down to choosing four parameters, only two of which you really have to think about.

            • V: the prior mean variance (or the prior mean covariance matrix, if you have a multivariate random effect term). According to the course notes, "without loss of generality V can be set to one" (or in the case of a multivariate model, to an identity matrix)
            • alpha.mu: we almost always want this to be zero (or as in your example, a vector of zeros); that way the prior for the standard deviation will be a Student t distribution. (There may be a use case for alpha.mu != 0, but I've never run across it.)
            • alpha.V: with V set to 1 (or an identity matrix), this is the prior mean of the covariance matrix. A diagonal matrix with a reasonable scale for your problem is a good choice
            • nu: the shape parameter; as nu → ∞ we get a half-Normal prior for the standard deviations, with nu=1 we get a Cauchy distribution. Smaller values have fatter tails (less conservative/allowing broader samples, but also giving more danger of weird sampling behaviour in the tails).

            For the univariate case Hadfield says the t prior with V=1 is

            No vulnerabilities reported

            Install g2

            Build 100.xx has a number of changes, mostly related to extending Gcode support and supporting 3D printing using g2core. These include temperature controls, auto-bed leveling, planner performance improvements and active JSON comments in Gcode. Communications has advanced to support a linemode protocol to greatly simplify host communications and flow control for very rapid Gcode streams. Please read the Communications pages for details. Also see the NodeJS communications module docs if you are building a UI or host controller. Build 100.xx also significantly advances the project structure to support multiple processor architectures, hardware configurations and machine configurations in the same code base. Motate has been cleaved off into its own subproject. We recommend carefully reading the Dev pages if you are coding or compiling.
            Gcode and CNC Changes Included G10 L1, G10 L10, G43, G49 tool length offset and added 16 slot tool table (deferred until build 100.12) Included G10 L20 offset mode Extended G38.2 probing to also include G38.3, G38.4, G38.5 Homing can now be set to a non-zero switch. Homing will set to the travel value of the positive or negative switch, as determined by the search direction. This allows homing to home to a maximum - for example - and set the homed location to the non-zero switch. [100.13] Fixes for dwells mixed with gcode moves. [100.13] Minor planner refactoring to better handle commands and gcode mixed. (Forward-planning now looks past commands.) [100.13] Experimental! Optioan TRAVERSE_AT_HIGH_JERK (defaults to off, set to 1 in a settings file to enable) will make traverse moves (G0) use the high-jerk settings instead of the normal jerk settings. This applies to all axes universally.
            Planner and Motion Changes Junction Integration Time - the {jt:...} parameter is now the way to set cornering velocity limits. Cornering now obeys full jerk limitation instead of the centripetal acceleration heuristic, making it much more accurate and more true to the jerk limits set for the machine. JT is a normalized scaled factor that is nominally set to 1.000. Set to less than 1 for slower cornering (less aggressive), greater than 1 (but probably less than 2) for more aggressive cornering. This parameter replaces Junction Acceleration {ja:...} and the axis Junction Deviation commands - e.g. {xjd:0.01}. Deprecated {ja:...} global parameter. Will return error. Deprecated {_jd:...} per-axis parameter. Will return error.
            3D Printing Support Planner improvements to handle extreme cases found in some 3DP slicer outputs Added automatic bed leveling {tram:t} using 3 point probe and coordinate rotation Added {he1:n}, {he2:n}, {he3:n} heater control groups Added {pid1:n}, {pid2:n}, {pid3:n} ADC PID groups Note: The semantics of {he:...} and {pid:...} are still in development and may change.

            Active JSON comments - i.e. JSON called from Gcode Added M100 ({...}) active comment. Currently only supports temperature setting command. Added M101 ({...}) "wait-on-event" active comment. Currently only supports temperature wait command. Additional note: M101 will only wait on values that return true or false, and will only work if given true or false. Valid example: M101 ({in1: true}) Using 0 or 1, or anything except true or false will not work.
            System and Communications [100.27] Adding motor object keys ep "enable polarity" and sp "step polarity" to allow having the step and enable pins use inverted polarity [100.13] Important: USB will only expose one virtual serial port by default. This can be overridden in the settings file with: // Valid options are 1 or 2 only! #define USB_SERIAL_PORTS_EXPOSED 1 [100.13] Refactored XIO to handle !, %, ~, and JSON commends intermixed with gcode better. [100.13] Fixes to USB connection, initialization, and DMA operation for Sam3X-base machines. Added Linemode communication protocol, and provide guidance to use linemode for much simpler and more reliable application-level flow control Footer format has changed. Checksum is no longer supported and has been removed Added ENQ/ACK handshake. If the host sends an ASCII ENQ (0x05) the board should respond with an ACK (0x06).

In short, inputs are now just numbered inputs that are mapped to axes, functions, and motion behaviors (feedholds). Your configurations will need to change to accommodate these changes. See settings/settings_shapeoko2.h for an example of setup and use - pay particular attention to axis settings and the new inputs section. Typing $, $x, $di, $in at the command line is also informative. Of course, all these commands are available as JSON, but in text mode you get the human readable annotations. These changes also rev the firmware version to 0.98 from 0.97, as a new configuration wiki page will need to be generated (not started yet). {lim:0}, {lim:1} was added to allow a limit override to backing off switches when a limit is tripped See also Alarm Processing, which is intimately related to these changes.
            Alarm processing has been significantly updated. There are now 3 alarm states: ALARM - used to support soft and hard limits, safety interlock behaviors (door open), and other conditions.

PANIC - shuts down the machine immediately if there is an assertion failure or some other unrecoverable error CLEAR describes how to clear alarm states.
            Job Exception Handling has been refined. A new Job Kill has been introduced which is different than a queue flush (%), as these are actually 2 very different use cases.
            Homing changes. Homing input switches are now configured differently. The switch configurations have been removed from the axes and moved to the digital IO inputs. Two new parameters have been added to the axis configs. All other parameters remain the same. {xhd:1} - homing direction - 0=search-to-negative, 1=search-to-positive {xhi:N} - homing input - 0=disable axis for homing, 1-N=enable homing for this input (switch) Note that setting the homing input to a non-zero value (1) enables homing for this axis, and (2) overrides whatever settings for that input for the duration of homing. So it's possible to set di1 (Xmin) as a limit switch and a homing switch. When not in homing it will be used as a limit switch.
            Safety Interlock added An input configured for interlock will invoke a feedhold when the interlock becomes diseangaged and restart movement when re-engaged. {saf:0}, {saf:1} was added to enable or disable the interlock system. There are optional settings for spindle and coolant actions on feedhold. See below
            Spindle Changes Expect updates to spindle behaviors in future branches. Here's where it is now: The spindle can be paused on feedhold with the Spindle-pause-on-hold global setting {spph:1}. For now we recommend not using this {spph:0} as there is not yet a delay in spindle restart. Spindle enable and direction polarity can now be set using the {spep: } and {spdp: } commands. Spindle enable and direction state can be returned using {spe:n} and {spd:n}, and these can be configured in status reports Spindle speed can be returned using {sps:n} and can be configured in status reports
            Coolant Changes Expect coolant changes in future branches, in particular to accommodate changes in the digital outputs. The coolant can be paused on feedhold with the Coolant-pause-on-hold global setting {coph:0}. Flood and mist coolant polarity can now be set using the {cofp: } and {comp: } commands. Flood and mist coolant state can be returned using {cof:n} and {com:n}, and these can be configured in status reports In v9 the flood (M8) and mist (M7) commands are operative, but map the same pin. M9 clears them both, as expected. These should both be set to the same polarity for proper operation. On a Due or a platform with more output pins these can be separated - the code is written for this possibility. The changes should be limited to the pin mapping layers.
            Power Management is fully working, as far as we can tell. See $1pm for settings
            Arc Changes have been added. Please note any issues immediately. This is still under test.
            Fixed bug on very large arcs
            Fixed bug on G18 rotation direction
            Added P parameter to allow for arcs > 360 degree rotation
            G10 L20 was added for easier offset setting
            Bug Fixes Fixed some units mode display errors for G20 mode (inches)
            Still To Go SD card persistence Spindle restart dwell Digital output generalization and changes Still needs rigorous testing for very fast feedhold/resume and flush cycles
            No Persistence. Most ARM chips (including the ATSAM3X8C on v9 and ATSAM3X8E on the Arduino Due) do not have persistence. This is the main reason the v9 has a microSD slot. But this has not been programmed yet. So your options are to either load the board each time you fire it up or reset it, or to build yourself a profile and compile your own settings as the defaults. Still working on feedhold. The serial communications runs a native USB on the ARM instead of through an FTDI USB-to-Serial adapter. We are still shing some bugs out of the single character commands such as feedhold (!), queue flush (%) and cycle start (~). Power Management needs work. It doesn't always shut the motors off at the end of a cycle. Different Behaviors. There are some behaviors that are different.

            Different Behaviors. There are some behaviors that are different. Feedhold / queue flush on v8 works with !%~ in one line. In g2 it requires a newline. Use !\n%\n This is due to using a USB stack that is partly on the chip and not being able to get at the individual characters that far upstream. This will probably not change in v9.
