LMlike-class: Linear Model-like Class

Description

Wrapper around modeling function to make them behave enough alike that Wald tests and Likelihood ratio are easy to do. To implement a new type of zero-inflated model, extend this class.

Usage

# S4 method for LMlike
summary(object)
# S4 method for LMlike,CoefficientHypothesis
waldTest(object, hypothesis)
# S4 method for LMlike,matrix
waldTest(object, hypothesis)
# S4 method for LMlike,character
lrTest(object, hypothesis)
# S4 method for LMlike,CoefficientHypothesis
lrTest(object, hypothesis)
# S4 method for LMlike,Hypothesis
lrTest(object, hypothesis)
# S4 method for LMlike,matrix
lrTest(object, hypothesis)

Arguments

object

LMlike

hypothesis

one of a CoefficientHypothesis, Hypothesis or contrast matrix.

Methods (by generic)

  • summary: Print a summary of the coefficients in each component.

  • waldTest: Wald test dropping single term specified by CoefficientHypothesis hypothesis

  • waldTest: Wald test of contrast specified by contrast matrix hypothesis

  • lrTest: Likelihood ratio test dropping entire term specified by character hypothesis naming a term in the symbolic formula.

  • lrTest: Likelihood ratio test dropping single term specified by CoefficientHypothesis hypothesis

  • lrTest: Likelihood ratio test dropping single term specified by Hypothesis hypothesis

  • lrTest: Likelihood ratio test dropping single term specified by contrast matrix hypothesis
