Arguments

object glm or lm type

Details

This test asks whether the model with predictors fits significantly better than a model with just an intercept (i.e., a null model).

The test statistic is the difference between the residual deviance for the model with predictors and the null model. The test statistic is distributed chi-squared with degrees of freedom equal to the differences in degrees of freedom between the current and the null model (i.e., the number of predictor variables in the model).
