_No_ program can "figure out the relationship" between a response 
variable and given predictor variables. But Mathematica can certainly 
find a linear model fit with multiple predictor variables -- provided 
that's an appropriate model for you to use. The function LinearModelFit 
does this.

Perhaps your data are such that you really want some nonlinear model. 
You specify the form of the model (as a function of the predictor 
variables) and then use NonlinearModelFit to let Mathematica determine 
the parameters of the model.
