Wrapper for lmer/glmer

Source: R/AllClasses.R, R/lmWrapper-glmer.R

A horrendous hack is employed in order to do arbitrary likelihood ratio tests: the model matrix is built, the names possibly mangled, then fed in as a symbolic formula to glmer/lmer. This is necessary because there is no (easy) way to specify an arbitrary fixed-effect model matrix in glmer.

# S4 method for LMERlike
update(object, formula., design, keepDefaultCoef = FALSE, ...)

# S4 method for LMERlike
vcov(object, which, ...)

# S4 method for LMERlike
coef(object, which, singular = TRUE, ...)

# S4 method for LMERlike
logLik(object)

Arguments

object

LMERlike

formula.

formula

design

something coercible to a data.frame

keepDefaultCoef

logical. Should the coefficient names be preserved from object or updated if the model matrix has changed?

...

In the case of vcov, ignored. In the case of update, passed to model.matrix.

which

character, one of 'C', 'D'.

singular

logical. Should NA coefficients be returned?

Value

see the section "Methods (by generic)"

Methods (by generic)

  • update: update the formula or design matrix

  • vcov: return the variance/covariance of component which

  • coef: return the coefficients. The horrendous hack is attempted to be undone.

  • logLik: return the log-likelihood

Slots

pseudoMM

part of this horrendous hack.

strictConvergence

logical (default: TRUE) return results even when the optimizer or *lmer complains about convergence

optimMsg

character record warnings from lme. NA_character_ means no warnings.
