I'm looking for an iOS program that can calculate some statistics for me.
I want a program into which I can enter a bunch of observations, then the program uses multivariate linear regression (ordinary least squares) to find coefficients and standard errors for the line of best fit. I know of plenty of programs that do this on the Mac, but not any iOS programs.
There aren't any programs in the app store that list this as one of their key features, but I didn't know if it was an additional feature in something like Numbers. Alternately, while I'd prefer not a web app, that's certainly better than not having an app to do this. A web app that uses local storage so it can run even when offline would be best.
