I am using estout (SSC) on Stata 16.1 to tabulate the results of a multinomial logit regression. I would like to label each column with the categories that are being compared in it (i.e., Base vs. Category N). I am running the following code (as a toy example):

Code:
webuse auto
qui mlogit rep78 weight length turn displacement, base(1)
est store mlogit
estout mlogit, stats(r2_p N, labels("Psuedo R-Squared" "N")) cells(b(star fmt(4)) se(par fmt(4))) label unstack collabels("1v1" "1v2" "1v3" "1v4" "1v5")
Results:
Code:

I am following the syntax suggested on the estout website to specify the column labels individually, but when I do the column label repeats itself. Is there any way to work around this?

Additionally, is there a way to avoid reporting the blank column for the reference category (first column in the example)?

Thanks!
