QUESTION
I have placed my two plots side by side. However, I have noticed that the plots have been shaped to be the same size, and this has caused the distribution curves to appear the same when I know they are not. The Cobalt curve should be shorter and fatter than the Rhodium curve.
...ANSWER
Answered 2022-Apr-17 at 07:26As you have pointed out, the range difference between the two distributions is substantial. You could try to set ax1.set_xlim
, ax1.set_ylim
, ax2.set_xlim
, ax2.set_ylim
, but in my opinion at least one subplot would end up to be hardly legible.
What if you combine the two subplots into one?

QUESTION
I'm using the MatchIt package in R to conduct coursened exact matching. When I complete the matching and check the balance using cobalt, I'm told that the Diff.Adj is 0.00 for my categorical variables, and -0.06 for the continuous variable.
However, when I then create a table in gtsummary, the standardized difference scores for those variables are 0.65 for the categorical variable and 0.30 for the continuous variable.
Can anyone explain the discrepancy between the two packages?
In gtsummary I'm piping the table to add_difference(everything() ~ "smd")
.
ANSWER
Answered 2022-Mar-23 at 19:52There are many possible reasons for differences you observe. Given that you have not supplied a minimal reproducible example or any output, we can only speculate. I am the author of MatchIt
and cobalt
so I can explain the choices there (which are the same) and how I justify them.
For continuous variables, the SMD after matching is the difference in the means (weighted by the matching weights) divided by a scaling factor computed in the original sample. I have justified the choice to compute the standardization factor in the original sample here and elsewhere. The standardization factor depends on the chosen target population, but it can be changed by supplying an argument to s.d.denom
. By default, when matching for the ATT is used (the default in MatchIt
), the standardization factor is the standard deviation of the variable in the treated group (again, computed prior to matching). When matching for the ATE, the standardization factor is the square root of the average of the variances in the treatment groups. The defaults and allowable arguments are explained in help("col_w_smd")
.
For categorical variables, cobalt
first splits them into dummy variables for each category and then treats the dummy variables as independent variables. By default cobalt::bal.tab()
produces unstandardized mean differences (i.e., raw differences in proportion) for binary and categorical variables. If you want standardized mean differences, you need to set binary = "std"
. I explain in the documentation why I think standardized mean differences don't make sense for binary variables. cobalt
uses a special formula for the variance of binary variables (smd
does as well), so be sure to take that into consideration when trying to replicate cobalt
's results manually.
I am not sure exactly what smd
(which is the basis for calculations in gtsummary()
) does, because its documentation is somewhat sparse and its code (which uses an R6 architecture) is hard for me to read (though, admittedly, cobalt
's is too). It seems like smd
computes the standardization factor in the matched sample when matching weights are supplied (or only the matched sample is supplied to it), and it always computes the standardization factor as the square root of the average of the variances in the treatment groups. For categorical variables, it compute a single standardized mean difference for the whole variable using the formula described in Yang & Dalton (2012) rather than splitting the variable into separate dummy variables. I explain here why I don't think this is a great idea.
Hopefully this sheds some light on these differences. I would encourage you to use cobalt
rather than gtsummary()
for producing balance tables because of the amount of research that went into choosing these settings. They represent what, in my opinion, are best practices. cobalt
also gives you the flexibility to supply your own choices if you don't agree, but by making those choices yourself, you get to know exactly how each value is calculated. I have also worked hard to ensure cobalt
is thoroughly documented to help users understand exactly what is going on. Everything I described about cobalt
's functionality is explained in the documentation.
QUESTION
I have a list of links I want to serve data randomly from, as if the user manually went to the url themselves. These are not all the same content/file type, however they are all images (jpeg and png) (Ideally I would like to do this with any file type, not just jpeg and png or just images). I know I can serve them directly as an octet stream like this, but this will result in the files being downloaded, instead of being displayed inline. I have considered changing the content type based on the link extension, but I can't find any information on how to use content types that are unknown at compile time. I also feel like there might be a better way than that. How to forward data from a reqwest::blocking::Body in a Rocket responder? Seems to be somewhat similar to my question, however the file type is always png. I am using v0.5-rc
of rocket.
ANSWER
Answered 2022-Feb-09 at 06:14I ended up downloading the image data, storing it in memory, and returning a content type and the image data.

QUESTION
I am writing a Lua filter for pandoc that adds a glossary function to HTML output of a markdown file. The goal is to add mouseover text to each occurrence of an acronym or key definition in the document.
I would like to be able to include acronyms when they occur in a list (surrounded by punctuation), but not by letters (e.g. so CO isn't highlighted in a word such as cobalt).
My MWE fails on this count because strings in the Pandoc AST include adjacent punctuation (e.g. Str "CO/DBP/SBP,"
or Str "CO,",Space,Str "SBP,"
).
ANSWER
Answered 2021-Sep-21 at 12:26You can just return a table with multiple elements. My idea was to look for the first separator and then replace the glossary entries with spans:
