marginsplot

[Paul Lambe]

Dear Statalist
I have successfully used the new gsem latent class analysis command in Stata15 however when I use margins and marginsplot to visually compare the probabilities across classes I get a single plot line rather than a bar graph depicting the probabilities of the categorical variables in the model within each of the three latent classes. I followed the commands in the example provided by Stata at https://www.stata.com/new-in-stata/l...lass-analysis/
Any help would be greatly appreciated.

They don't give the marginsplot command and I doubt it was just "marginsplot". Note the options for recasting the plot type and plotting with a by variable are available in marginsplot.

Hi Dave
many thanks. Already tried recast (bar) but not sure on command to obtain by var. Will keep trying.

bydimension(dimlist [, dimopts])

There is an example using this option.

Hi Dave
where can I find the example?

In the help for marginsplot there are a few examples one of which is:

. marginsplot
. marginsplot, xdimension(agegrp)
. marginsplot, xdimension(agegrp) bydimension(sex)
. marginsplot, xdimension(agegrp) bydimension(bmi) xlabel(, angle(45))

I'm using version 14.2.
