Beta-Surface

This is another visualization of the predictive model I'm working with.

From front to back on the X axis are ranks of subjects (ranked by probability of purchase).

On the Y axis (from left to right are individual variables in the model).

Z axis is the mean xbeta, (basically variable * weight).

I've colored them by their standard deviation, so grey-orange-red is pretty low variation.

The 3D isn't that great (I'm still figuring out gnuplot), but it's still super interesting to see what's going on inside the machine.
