If only one fitted model object is specified, it is compared to the trivial model (with only an intercept). R package. lheure-vin.com Created by lheure-vin.com Wald test for a term in a regression model Description. Provides Wald test and working likelihood ratio (Rao-Scott) test of the hypothesis that all coefficients associated with a particular regression term are zero (or have some other specified values).
