hi all,
I have 45 continuous variables with 500 observations. i have been reading about creating graph bars with error bars (std or SEM) but i am bit overwhelmed by the many propositions from statlist members, which don't seem intuitive for me (just started learning stata). can you please help me with a simple code that will calculate the mean and the SD or SEM, plot bars with SD or SEM or CI.
thanks in advance
