I think I want to use "dirifit" to test differences between four dependent proportions (e.g., the proportion of presses on each one of four relevant keys during a task) but without another explanatory variable (e.g., gender), does anyone can advise me what is the correct Stata command?
In my data each participant has four dependent proportions e.g., .30, .25, .10, 35 (sum=1). what significant test and Stata command should I use to test the difference between those proportions?
thank you!
