Dear Austin,

Based on the code you suggested, I have the following:

loc c vioplot bw [pw=finalwgt]
`c' if motherland3==1, ti(`:lab Sweden') den(col(blue)) name(e1)
`c' if motherland3==2, ti(`:lab NA') den(col(green)) name(e2) ysc(off)
`c' if motherland3==3, ti(`:lab Iran') den(col(edkblue)) name(e3) ysc(off)
gr combine Sweden NA Iran, nocop ycommon row(1) name(vio)
byhist bw, by(motherland3) frac tw(leg(col(1)))


- where bw is the continous outcome whose distributions I would like to produce by the categorical variable motherland3 which has 10 categories.

- I've just wirtten the lines for the first 3 categories of the motherland3 variable above.

-However I keep getting a error message that the line 'c' if motherland3==1....' is invalid syntax. Could you please tell me what I'm doing wrong and what exactly the 'c' signifies?

I also want to know what the (pw=finalwgt) does.

Thanks a lot!

Regards,

/Amal.
