The program is for a class, it is a sensor data gathering and graphing program for the Palm OS. I have definitely looked, there is no easy drop in that I can use. Unfortunately, it cannot just be dropped from the program either.
Logarithmic I have figured out in a linear way. I'll give that a try Telperion, that definitely looks like the easy to understand version of the few directions that I have found.
Engineering statistics textbooks, at least the few that I have looked at, that me and my friends have used for our statistics classes, stop at linear regression. The general statistics classes that are required here are not too difficult, many topics were not covered because they involved calculus, and that was determined to be outside the difficulty of the class.
As for my matrix math skills, not too bad, but not all that great. I can understand all the matrix operations going on on the board right now in Cryptography, if that gives you any idea of my skills.
