st: Sequential or hierarchical regression

["Alan Acock" <acock@comcast.net>]

I am doing a sequential multiple regression where I start with the base
model: y = a + b1x1 + b2x2

followed by the full model: y = a = b1x1 + b2x2 + b3x3 + b4x4

==================================================
Try findit hireg and install this program. It does what you want if I
understand you correctly.
