Can anyone help? > You can enter any equation into the y= list by enclosing it in quotes and then storing it into the appropriate y=. For instance, "2x+3"->y2 Now, the next logical step would be to store the RegEQ in some y. But, when I tried this on my TI-82 it pasted the current RegEQ while I was programming. NOT GOOD. All is not lost though. I was able to use the coefficient variables in my equation. Thus you need to know the type of regression curve your using. For instance, for a cubic regression: ClrHome CubicReg L1,L2 "aX^3+bX^2+cX+d"->y1 I hope this helped a little. -- Marc Dancer Voice (413)-774-6269 Deerfield Academy FAX (413)-774-6629 Deerfield, MA 01342 EMAIL mdancer@k12.ucs.umass.edu
