Purpose

Estimate the coefficients of a NAR model

Description

"NAR modeling" calculates the least-squares estimates of the coefficients of a Nonlinear Auto-Regressive (NAR) model involving linear and bilinear terms of lagged values of the response signal,

The input signal y is regarded as NAR model response. The output signal r is the residual, i.e. the estimation error.

Parameters are:


Besides the estimated coefficients, a residual constant term, the mean of the residues, the residual variance, and the normalized residual variance are displayed in the message window.

Macro Synopsis

r = NARmodel(y,K,M);
