logLik.lmeStruct {nlme}R Documentation

Log-Likelihood of an lmeStruct Object


Pars is used to update the coefficients of the model components of object and the individual (restricted) log-likelihood contributions of each component are added together. The type of log-likelihood (restricted or not) is determined by the settings attribute of object.


## S3 method for class 'lmeStruct'
logLik(object, Pars, conLin, ...)



an object inheriting from class "lmeStruct", representing a list of linear mixed-effects model components, such as reStruct, corStruct, and varFunc objects.


the parameter values at which the (restricted) log-likelihood is to be evaluated.


an optional condensed linear model object, consisting of a list with components "Xy", corresponding to a regression matrix (X) combined with a response vector (y), and "logLik", corresponding to the log-likelihood of the underlying lme model. Defaults to attr(object, "conLin").


some methods for this generic require additional arguments. None are used in this method.


the (restricted) log-likelihood for the linear mixed-effects model described by object, evaluated at Pars.
