Dear List members,
I have a question and I hope to have your help. In any research with any kind of analysis the number of subjects should be logical to find more reliable results. I know, based on what is mentioned in www.winsteps.com , using Rasch the number of subjects will increase generalizability of our finding to other situation.
I wonder, if there is any formula to consider the number of variables when we decide about the number of subjects. having 300 subjects is great but for how many variables?
I appreciate your help in advance.
