Power Analysis--Logistic Analysis

[ssulli11]

Good evening!

I am new to using the proc power procedures and am having difficulties getting started.

I am looking to do a sample size power analysis for a logistic regression and Chi-square analysis.  I have found the following online, but am still quite lost.

Is there anyone that has a good simple procedure with some minor explanation to get me started?  I simply want to know what sample size I need for sufficient power in my analysis.

As always, thank you for your guidance and expertise!  

As always, I appreciate your help!

You may find this paper Power Analysis for Generalized Linear Models Using the New CUSTOM Statement in PROC POWER and the accompanying video useful.

Chapters 4 and 14 in SAS for Mixed Models: Introduction and Basic Applications will be particularly useful for statistical models that are more complex.

I hope this helps.
