Hi to everybody,
Please does anybody can help me to solve this problem?
I have a multiple logistic regression model with more than one BINARY INDEPENDENT VARIABLES.
I need to calculate the minimum required sample size for my study, and I perfectly know how to calculate that for a model with only one binary independent variable (http://www.psycho.uni-duesseldorf.de/abteilungen/aap/gpower3/user-g...
But I cannot find on web any material or documentation illustrating a solution to the problem with a multiple logistic regression model with more that one binary independent variables
Will you, please, help me?????
I'd appreciate it very very much.
