Worry about the multiple outputs these tell what types of regression you need ESPECIALLY IF THEY ARE OF DIFFERENT TYPES. ONCE YOU KNOW THAT ASK AGAIN.Best wishes David Booth
You can use Multi-linear regression however if you need to find two output variables predicted by some other variables. you need to try a different approach.
Probably, you can predict those response variables with the predictor variables separately. Before selecting the predictor variables to estimate the predictor variables you might have to do a factor analysis.
