### Re: Joint probabilities of statistically non-independent eve

This isn't fundamentally a problem for regression, because the goal of regression is to find the function relating independent and dependent variables which you already have; I'm trying to estimate the values of a set of independent variables based on the values of some dependent variables and some...

Is there a reason that a regression with interaction terms wouldn't work? Then you can include terms for serial autocorrelation to account for maturation.
