Proc Power- logistic statement, SAS 9.3

Hello,

I am attempting to run a power analysis on a binary data set, and all of the literature I've read suggests I should start this with a logistic statement, such as:

Proc power;

logistic

...followed by the variable specifications.

However, SAS 9.3 does not seem to recognize the logistic statement, and leaves it in red text. By contrast, I can enter many of the other potential statements, such as onesamplemeans, onecorr, twosamplemeans, etc. and it seems to work- note that a semicolon does not need to follow the statement in this syntax. Does the logistic statement no longer work in PROC POWER in SAS 9.3? Is there another way to attempt a logistic power analysis?

Thanks,

James

It should work. I've encountered some instances where the color-coder uses the wrong color. That does not mean that the syntax is not supported, it just indicates that the color coding is wrong. Try it on a simple example.
