ganova {lmreg}

ANOVA table for linear hypothesis in a linear model

Description

Prepares Analysis of Variance table for testing a general linear hypothesis in a linear model

Usage

ganova(y, X, A, xi, tol=sqrt(.Machine$double.eps))

Arguments

y

Responese vector in linear model.

X

Design matrix or matrix containing values of explanatory variables (generally including intercept).

A

Coefficient matrix (A.beta = xi is the null hypothesis to be tested).

xi

A vector (A.beta = xi is the null hypothesis to be tested).

tol

A relative tolerance to detect zero singular values while computing generalized inverse, in case the model matrix is rank deficient (default = sqrt(.Machine$double.eps)).

Value

Returns analysis of variance table for testing A.beta = xi in the linear model with response vector y and matrix of explanatory variables/factors X.
