kandi X-RAY | coefplot Summary
Coefplot is a package for plotting the coefficients and standard errors from a variety of models. Currently lm, glm, glmnet, maxLik, rxLinMod, rxGLM and rxLogit are supported. The package is designed for S3 dispatch from the functions coefplot and getModelInfo to make for easy additions of new models. If interested in helping please contact the package author.

QUESTION
I want to plot the coefficients from this regression as a forest plot.
...ANSWER

automatically excludes coefficients that are flagged as "omitted" or as "base levels"---as in the case of your coefficients. To include all coefficients in the plot, you should specify the "omitted" and "baselevels" options. So it would look like something along these lines:
QUESTION
I am working on coefplot and I would like to readjust the legend size of the labels to vsmall. However, when I use labsize(vsmall)). I get an error. Am I missing a specific step within coefplot?
...ANSWER

from your command entirely, and add legend(size(vsmall))
to the end of your command as an option. Your final command should look like this:

Answered 2021-Nov-10 at 09:25If you read the stata documentation for smoothed ci plot, it's actually from David Sparks who provided the code here. You just need to alter it slightly to make it side by side.

instead of qplot()

QUESTION
I am using geom_point() with ggplot to essentially create the equivalent of a -coefplot- with coefficients of 5 different models on one plot.
Is it possible for me to change the color of just one point (and corresponding CI bars)? What about the color/font/etc. of an individual axis tick label? For example, if I only want to make the font bold for the label for Model 3 and make Model 3's coefficient point (+ CI bars) red (or any other color to distinguish it). I've tried scale_fill_manual
but that didn't seem to do the trick.
My current code (with scale_x_discrete, the names of the models are just Model 1, 2, 3, etc. and I'm putting them in order there):
...ANSWER
Answered 2021-Aug-19 at 03:38You can use a condition to color only the point and CI that you want. ifelse(test to select your group, color name if yes, color name if not)

QUESTION
I am creating three coefficient plots with the same variables and want them to be one next to each other, but the third one does not fit horizontally so it appears under the other two. My code is
...ANSWER
Answered 2021-Jul-20 at 10:31The problem is probably not because of lack of space, but rather because you don't specify the option byopts(compact rows(1))
. If you want all pots on one row or one column, you need to specify that. It's hard to tell without a reproducible example, though.
You probably know this webpage, but it's also explained here, in the section "How subgraphs are combined": http://repec.sowi.unibe.ch/stata/coefplot/getting-started.html
QUESTION
I am using the coefplot
command in Stata to plot coefficients and confidence intervals from multiple regression models. I am plotting the same coefficient (X) from 4 different model specifications.
There is one model specification (alternative standard errors) that I cannot figure out how to estimate in Stata, but am able to estimate using R. That means that for one model specification, I have the standard error in R, but not in Stata.
Is there an easy way to manually alter the standard errors in coefplot?
My code is:

Answered 2021-Apr-29 at 10:45You can manually edit the e(V)
(variance-covariance matrix) and e(b)
vectors. For this, define a program:
QUESTION
Most of the time we run a regression with interactive terms, we are interested in a partial derivative. For example, consider the model below,
If I am interested to know the effect of X1 on P(Y), or the partial derivative of X1 on P(Y), I need the following combination of coefficients:
Instead of calculating it by hand, I can use, for example, the lincom function in R to calculate linear combination of regression parameters. But I would like not only to know the numbers from calculations like this; I would like to plot them. The problem is, if I am using a R package to plot coefficients (e.g., coefplot) it plots the coefficients from my model, but with no option for linear combination of coefficients. Is there any way to combine the lincom function (or other function that calculates combination of parameter) with coefplot (or other coefficient plot packages with this option)?
Of course, in the example above I only consider the derivative of X1, and if I plot it I will have a plot with one dot and its confidence intervals only, but I would like to show in the plot the coefficients for the partial derivatives of X1, X2, and Z, as in the example below.
Coefficients plot (the one I have):
Combination of parameters or partial derivatives plot (the one I am trying to get):
I discovered that Stata has a function that does what I am looking for, called "plotbeta." Does R have something similar?
