Polyfit: Polyfit

In shapelets/khiva-r: KHIVA-R library.

Description

Least squares polynomial fit. Fit a polynomial p(x) = p[0] * x^{deg} + ... + p[deg] of degree deg to points (x, y). Returns a vector of coefficients p that minimises the squared error.

Usage

Polyfit(x, y, deg)

Arguments

x	KHIVA array with the x-coordinates of the M sample points (x[i], y[i]).
y	KHIVA array with the y-coordinates of the sample points.
deg	Degree of the fitting polynomial

Value

: KHIVA array with the polynomial coefficients, highest power first.
