Many ANOVAS for count data with Poisson or quasi Poisson models

Description

Many ANOVAS for count data with Poisson or quasi Poisson models.

Usage

colpoisson.anovas(y, x, logged = FALSE) 
colquasipoisson.anovas(y, x, logged = FALSE) 

Arguments

y	A numerical vector with the data.
x	A matrix with the data, where the rows denote the samples (and the two groups) and the columns are the variables. This must be a matrix with the categorical variables as numbers, starting from 1. Poisson or quassi Poisson ANOVA takes place for each column.
logged	A boolean variable; it will return the logarithm of the pvalue if set to TRUE.

Details

Poisson or quassi Poisson ANOVA takes place at each column.

Value

A matrix with the test statistic and the (logged) p-value for each predictor variable. In the case of the quasi Poisson, the \phi is returned as well.
