QUESTION
I'm trying to calculate the mean, standard deviation, median, first quartile and third quartile of the lognormal distribution that I fit to my histogram. So far I've only been able to calculate the mean, standard deviation and median, based on the formulas I found on Wikipedia, but I don't know how to calculate the first quartile and the third quartile. How could I calculate in Python the first quartile and the third quartile, based on the lognormal distribution?
...ANSWER
Answered 2021-Jun-08 at 20:07Given a log-normal distribution, we want to compute its quantiles. Furthermore, the parameters of the log-normal distribution are estimated from data.
The script below uses OpenTURNS to create the distribution using the LogNormal
class. It takes as inputs arguments the mean and standard deviation of the underlying normal distribution. Then we can use the computeQuantile()
method to compute the quantiles.

QUESTION
I am trying to fit a log-normal distribution to the histogram data. I've tried to follow examples of other questions here on the Stack Exchange but I'm not getting the fit, because in this case I have a broken axis. I already put the broken axis on that plot, I tried to prevent the numbers from overlapping on the axes, I removed the numbers from the repeated axes, I reduced the size of the second subplot, but I'm not able to fit the log-normal. How can I fit the log-normal distribution for this data set?

...ANSWER
Answered 2021-Feb-21 at 03:54You're trying at the same time to do fancy graphs and fit. you help you with fit, graphs are secondary problem.
First, use NumPy arrays for data, helps a lot. Second, your histogram function is denormalized.
So if in the first of your programs I'll normalize freqs array
QUESTION
Starting from this lesson here: WebGL 3D Perspective I am triyng to implement Back-Face culling no magic.
I am computing on the fly the face normals in object space. After that, I am setting the fudgeFactor
inside m[2][3] to get the perspective divide by Z.
To check if the shear matrix works, I expanded my snippet using directly the vertex positions projected out of the WebGL vertex shader, and added the "projected position" flag.
Now, I am triyng to use the z-component inside the transformed normals to hide the faces with normal.z <0. This technique works well using orthogonal projection - or when fudgeFactor is 0. Why this doesn't work also for perspective projection, when I set the fudgeFactor
by my self?
To see what's happen, I wrote the minimal example below to visualize the normal vectors (thanks to: Geeks3D) and colored it. Green normal: face is visible, red normal: face is culled.
I followed the hints of gman and implemented the basic polygon rasterization (out of the WebGL vertex shader) as a proof of concept . Try to drag the fudgeFactor slider
and check that works correctly.
ANSWER
Answered 2021-Feb-05 at 03:00I'm sorry if this is not an answer to your question but "back face culling" has nothing to do with normals and you don't generally do it manually. You let WebGL do it for you
From the spec
3.5.1 Basic Polygon RasterizationThe first step of polygon rasterization is to determine if the polygon is back facing or front facing. This determination is made based on the sign of the (clipped or unclipped) polygon’s area computed in window coordinates. One way to compute this area is
where xiw and yiw are the x and y window coordinates of the ith vertex of the n-vertex polygon (vertices are numbered starting at zero for purposes of this computation) and i⊕1 is (i+1) mod n. The interpretation of the sign of this value is controlled with
QUESTION
I want to turn my Dataconstructor MP
into an instance of Num
MP
looks like this data MP = MP String
and the string is build only of + and - e.g. "++-+-+"
where every + represents a +1 and a - represents -1.
I also have already a function that normalize that string e.g. "++-+-+" to "++"
...ANSWER
Answered 2020-Nov-29 at 16:47You say:
I have tried
(+) (MP a) (MP b) = (a++b)
You are correctly writing a function that accepts values of type MP
, but you must also return a value of type MP
, as in (+) (MP a) (MP b) = MP (a ++ b)
. There are still bugs in that implementation, of course, but that should get you over the first hump and on to something you can play with further yourself.
QUESTION
I am trying to run MSBuild programmatically from a C# DLL (which will ultimately be loaded from PowerShell), and as a first step from a command-line application. I have used Microsoft.Build.Locator as recommended (or so I reckon) by installing its NuGet package to my project, and adding the following references to my test project:
...ANSWER
Answered 2020-Oct-03 at 04:45Actually, this is an real issue for a long time for packages.config nuget management format. And Microsoft's recommended solution for this problem is to add a bindingRedirect.
Usually, you can use this node in xxx.csproj
file to automatically generate bindingredirect.
However, for some specific dlls, this node may not work due to serveral reasons. And it is still an issue on the current packages.config nuget management format
as your said.
Suggestion
As a suggestion, you could use the new PackageReference nuget manage format instead since VS2017. This format is simple, convenient and efficient.
Also, when you use this format, first, you should make a backup of your project.
Just right-click on the packages.config
file-->click Migrate packages.config to PackageReference
.
Besides, I have also reported this issue on DC Forum and I hope the team will provide a better suggestion.

QUESTION
I use MOSEK to run a very large linear programming problem in Matlab (32768 unknowns and 691621 constraints). The code is submitted in a Linux based cluster. In the bash file I request the following amount of memory:
...ANSWER
Answered 2020-Sep-09 at 13:04Irrelevant in Matlab.
Irrelevant and imposible in Matlab. The MEX interface feeds the problem into Mosek in one go and takes care of all allocations itself.
For MSK_IPAR_NUM_THREADS to be respected you must restart the whole process i.e. Matlab. See https://docs.mosek.com/9.2/faq/faq.html#mosek-is-ignoring-the-limit-on-the-number-of-threads. However, when you set MSK_IPAR_INTPNT_MULTI_THREAD = 'MSK_OFF' then Mosek will use 1 thread regardless of the number of all threads available i.e. the number printed to the log is just an upper bound. You should be able to see in the task manager/top/whatever other CPU load tracker that only 1CPU is in use.
The basic question is: have you tried to run the problem without any memory limits to see if it works at all and estimate the memory consumption? Does it run on other machines?

docker-compose ps
will give you the state of your containers
2.
docker-compose stop
will stop your containers, keeping their state then you may start them as their are usingdocker-compose up
docker-compose kill
will delete your containersdocker-compose restart
will restart your containers
3.
By declaring your mongodb using an official mongo image your container start when you do
docker-compose up
without any other intervention.Or you can add
command: mongod --auth
directly into your docker-compose.yml
the official documentation of docker is very detailed and help a lot for all of this, keep looking on it https://docs.docker.com/compose/
