Linear Regression HP

[nsguy1350]

I need help on how to do a linear regression on an HP calc (HP32Sii). I try, but it doesn't work how I want it to.
What is wrong with X1 ENTER Y1 SUM, X2 ENTER Y2 SUM, X3 ENTER Y3 SUM... XN L.R. y
The sum memory is cleared when I do this.
Help please? I remember that I got it to work once, when I reverse the order that I entered the coordinates, or something. I tried again and didn't know what I did that made it work. Never figured it out.

I think on HP you have to enter the y coordinate first, then x coordinate.

Capybara is right, you do Y1 Enter X1, Y2 Enter x2, ...etc. then L.R. and find what your looking for, correlation coefficient, an x or y value, the slope, or the y-intercept.

Thanks! I reversed it once and it worked, but then I tried again and it didn't work. I'll see.

Clear your memory every-time when your going to work with linear regression, previous data will mess up results.

I do, I might have forgotten though, or maybe a wrong key-press or something.

Finally broke 200 on a calc test! (206)
I will flood you guys with questions later.
