Residual plots on the 50G/49G+
Message #1 Posted by Nick on 21 Sept 2006, 2:24 a.m.

Anyone know how to do one? HP doesn't appear to have any functions for making one, but they will calculate the least squares regression line. So what i'm asking is if there is a function to just fill in, for example, the third colum of my EDAT matrix with the values in colum 2 - the values on colum 1 plugged into the HP generated LSRL. Then we could just use a scatter plot. The problem is i have know idea how to do that. Is there any HP functions that i could use without having to write a program (becuase i don't know how)?
