    linear regression and statistical analysis in c

    hi,

    is there some package/source code that is out there that i can use for linear regression and statistical analysis (in particular, hypothesis testing and p-value generation)?

    i think the regression part is quite straightforward, as there are standard equations to use. but the hypothesis testing is rather tricky, with look-up tables and all that.

    thanks for any suggestion!

    I don't know what platform you're working on and whether you have any budget, but a quick Google search for "statistics libraries C" turned up several results. Do you have to solve this in C? If not, there's the R project. Note that I have zero experience with any of that stuff so I can't help you much with it, but hopefully it will be at least a little bit helpful.

    i am working on ubuntu. what i would like to do is carry out some simple statistical analysis on a 3D image (columns, rows, bands), for instance a linear regression on all the bands of a particular pixel, and then finding the p-value for the coefficients generated. this has to be done for all the pixels in the image, which number like a few million. so, i dont know if R can do this. but anyhow, i am not familiar with R.

    will this be simpler to do in matlab?

    Yeah, it would probably be easier in Matlab. If you end up having to use C however, I would probably go with GNU's GSL. I've never used it, but if it's anything like GMP or most of their other products, it's free, pretty solid and well documented.
