ZlmFit-class: An S4 class to hold the output of a call to zlm

Description

This holds output from a call to zlm.SingleCellAssay. Many methods are defined to operate on it. See below.

Usage

# S4 method for ZlmFit,CoefficientHypothesis
lrTest(object, hypothesis)
# S4 method for ZlmFit,Hypothesis
lrTest(object, hypothesis)
# S4 method for ZlmFit,matrix
lrTest(object, hypothesis)
# S4 method for ZlmFit,CoefficientHypothesis
waldTest(object, hypothesis)
# S4 method for ZlmFit,Hypothesis
waldTest(object, hypothesis)
# S4 method for ZlmFit
coef(object, which, ...)
# S4 method for ZlmFit
vcov(object, which, ...)
# S4 method for ZlmFit
se.coef(object, which, ...)

Arguments

hypothesis

call to Hypothesis or CoefficientHypothesis or a matrix giving such contrasts.

which

character vector, one of "C" (continuous) or "D" (discrete) specifying which component should be returned

...

ignored

Methods (by generic)

  • lrTest: Returns an array with likelihood-ratio tests on contrasts defined using CoefficientHypothesis().

  • lrTest: Returns an array with likelihood-ratio tests specified by Hypothesis, which is a Hypothesis.

  • lrTest: Returns an array with likelihood-ratio tests specified by Hypothesis, which is a contrast matrix.

  • waldTest: Returns an array with Wald Tests on contrasts defined using CoefficientHypothesis().

  • waldTest: Returns an array with Wald Tests on contrasts defined in Hypothesis()

  • coef: Returns the matrix of coefficients for component which.

  • vcov: Returns an array of variance/covariance matrices for component which.

  • se.coef: Returns a matrix of standard error estimates for coefficients on component which.
