Function polyFitBeta

Convenience function that takes a forward range X and a forward range Y, creates an array of PowMap structs for integer powers from 0 through N, and calls linearRegressBeta.

double[] polyFitBeta(T, U) (
  U Y,
  T X,
  uint N,
  double ridge = 0
);

Returns

An array of doubles. The index of each element corresponds to the exponent. For example, the X2 term will have an index of 2.
