Hello!
I'm attempting to write a program that will read in a bunch of data
points, perform a least squares fit to the points, and then draw the best
fit line. I know the basics behind writing the program, but I'm in need of
formulas that woud calculate m and b in y=mx+b. I know I should be able to
figure these out with a little bit of calculus, but the calculus seems to
lost on me! I also know that I should be able to do this using the Stats
button on my TI-85, but I want to be able to integrate this program between
the 85 and my PC. If anyone could mail me the formulas, I'd really
appreciate it!
Thanks,
Andrew
