Dear statalisters,
I wish to have a plot of multiple confidence intervals as follows:
| |.........................| (treat 1)
| |.....................................| (treat 2)
| |...............................| (treat 3)
| |.............................| (treat 4)
|
|-----------------------------------------------------------------
I have a continuous variable X measured over individuals on four treatment groups.
I have two variables Upper and Lower holding the upper and lower values above of the 95% C.I for each treatment mean(X). and a treatement-identifer variable (4 -categories). My aim first is to graph the four 95% C.I. as seen above and second to graph the overall all mean XBar (using the option xline(XBAR) cutting through the four 95 % C.I. above.
Is that possible with STATA.
Many thanks for your help in advance.
Amani
