Simple linear regression? #24

Closed ennerf closed 1 year ago

ennerf commented 1 year ago

I need to do a simple linear regression on an array of x/y values, but the ExampleRobustModelFit example needs multiple custom classes.

Is that the way to go or is that anything simpler that works out of the box?

Solved it with PolynomialFit from EJML
