Dear Stata Users,

I was wondering how I can use the qnorm command with the "by" option. I have carried out extensive simulations with different assumptions and sample sizes. The statistics of interest is normally distributed and I would like to show graphically that as the sample size increases the distribution of the statistic of interest gets closer and closer to that of the normal distribution in all conditions. I would like to avoid the combine command and use the by option since, if possible, it makes my life much easier - I do not have to save and maintain dozens of graphs.

Any suggestions on how I can achieve this task.

Many thanks in advance
