watex.utils.exmath.fitfunc

watex.utils.exmath.fitfunc(x, y, deg=None, sample=1000)

Create polyfit function from a specifc sample data points.

Parameters:

• x – array-like of x-axis.

• y – array-like of y-axis.

• deg – polynomial degree. If None should compute using the length of extrema (local + global).

• sample – int - Number of data points should use for fitting function. Default is 1000.

Returns:

• Polynomial function f

• new axis x_new generated from the samples.

• projected sample values got from f.
