Hi, Is there a SAS procedure that helps me identify if a sample size has too little observations? If I have # of accounts for 20 products and 10 years, so 20 rows and 10 columns. Is there a way to test if the # of accounts is too small (based on the whole portfolio - all 20 products), when I compare it to each product individually. Thanks
PROC POWER can help with the required sample sizes for analysis.
Thank you, I'll play with that.
