Multivariate linear regression
Hi,
I am working on a multivariate linear regression of the form y = Ax.
I am seeing a great dispersion of y w.r.t x. For example, the
correlations between y and x are very small, even after using some
typical transformations like log, power.
I tried with simple linear regression, robust regression and ace and
avas package in R (or splus). I didn't see an improvement in the fit
and
