Re: st: Output format after 'margins'

I personally use the -parmest- package, downloadable from SSC, to save results from -margins- in an output dataset (or resultsset) with 1 observation per estimated parameter and data on parameter names, estimates, confidence limits, P-values and other parameter attributes. To use -parmest- after -margins-, use the options

bmat(r(b)) vmat(r(V))

to extract parameter estimates and variances from the saved results from -margins-. The output dataset can be listed using the -list()- option, saved to memory (overwriting the pre-existing dataset) using the -norestore- option, or saved to a disk file using the -saving()- option. The on-line documentation for -parmest- contains hypertext references for further reading about the use of -parmest-.

I hope this helps.

Best wishes

Dear Statalists,

I often encounter calculation of adjusted means or ORs using
'margins', but don't know how to control the format of outputs, i.e.,
decimal numbers to present data in tables quickly. I have to do this
work manually by copying data to excel for manipulation, but it is
time-consuming. Does anyone have suggestions to make the work faster?
