Computes the likelihood ratio test for the coefficients of a generalized linear model.
1  lr.test(fit1, fit2)

fit1 
an object that stores the results of 
fit2 
an object that stores the results of 
The objects fit1
and fit2
are obtained using the usual options passed to the glm
function.
The function lrt.test()
returns the following list of values:
LR 
the value of the likelihood ratio statistic. 
pvalue 
the p value of test under null hypothesis chisquare distribution. 
Both fit1
and fit2
must have the same family
and link function.
