WebMar 22, 2024 · Description lrtest is a generic function for carrying out likelihood ratio tests. The default method can be employed for comparing nested (generalized) linear models (see details below). Usage lrtest (object, ...) ## Default S3 method: lrtest (object, ..., name = NULL) ## S3 method for class 'formula' lrtest (object, ..., data = list ()) Arguments WebDetails: The Harvey-Collier test performs a t-test (with parameter degrees of freedom) on the recursive residuals. If the true relationship is not linear but convex or concave the mean of the recursive residuals should differ from 0 significantly.

Recursive residuals may be used to detect functional misspecification in a regression equation. A simple t -statistic and a related Sign test may be constructed from the residuals. The powers of these tests compare favourably with the Durbin–Watson and other tests commonly used to detect functional misspecification … buying points mortgage
