Linear regression in 3 dimensions

Hi all,

I am seeking a module that will do the equivalent of linear regression in
3D to yield a best fit a plane through a set of points (X1, Y1, Z1), (X1,
Y1, Z1),... (Xn, Yn, Zn).

The resulting equation to be of the form:

Z = aX + bY + c

The function I need would take the set of points and return a,c & c Any
pointers to existing code / modules would be very helpful.

Many thanks,

You don't mention what you found lacking in the several possibilities
thrown up by googling "linear regression python" ...

I'm a little bit stuck with NumPy here, and neither the docs nor trial&error seems to lead me anywhere: I've got a set of data points (x/y-coordinates) and want to fit a straight line through them, using LMSE linear regression. Simple enough. I thought instead of looking up the formulas I'd just see if there isn't a NumPy function that does exactly this. What I found was "linear_least_squares", but I can't figure out what kind of...

Hi all, I am looking for a fast, efficient (tuned for speed, not size) and mature C++ code to do some numerical work with. I have looked at the Template Numerical Toolkit, which the oonumerics.org web page claims is a successor to lapack++. But on the surface it doesn't seem to have all the functionalities of lapack++, let alone being its successor. On the other hand, it may be faster. I haven't checked that yet. Lapack++ is supposed to...
