(01192019 01:46 PM)Gene Wrote: The HP 12c has linear regression built in. The slope has to be computed by calculating the difference in the predicted Yvalues for two Xvalues. This has already been discussed here, cf. http://www.hpmuseum.org/forum/thread618...l#pid55342 0 g [y^, r] => intercept 1 g [y^, r] => slope + intercept So this... Code: 1 ...returns the yintercept in X, the slope in Y and the correlation coefficient in Z and T. Also post #8 in that thread has essentially the same program as Gamo's, just without the double calculation of the determinant. Note: Gamo, I have sent a PM earlier today as you originally posted this to the Articles forum where no replies are possible. Dieter
