Fit a linear model f to data

Parameters:

• x (array-like, float) – Independent variable of length N

• y (array-like, float) – Dependent variable of length N

• delta (array-like, float (optional)) – Uncertainties on y

• f (array-like, callable) – Array of length Nf, of callables that evaluate each term in the linear model

Returns:

• p (array-like) – Estiamte of the Nf parameters
