It depends on what kind of "linear regression" are you interested in. For instance:
1. Just linear regression, as in y=a*x+b, or you'd also want power (y=a*x^b), logarithmic (y=a+b*ln(x)), etc ... fits ?
2. Just linear regression in one variable, as in y=a*x+b, or you'd also want linear regression for multiple variables: y=a0+a1*x1+a2*x2+a3*x3+...+an*xn ?
3. Just linear regression of degree 1, as in y=a*x+b, or polynomial regression of degree n: y=a0+a1*x+a2*x^2+...an*x^n ?
There are many possibilities with various degrees of complexity, you see.

I actually do have it for multiple variables. No, I need a quick number 1 in the list above (straight line, the others usually go by other names). I found the program from the Standard Pac, but then you said it's no good. I can do it on another HP of course (I'm really liking 34c), it's just I think I should have it on the 41CV as well, and this is the calculator I usually take to work.
