recalc.reStruct {nlme}R Documentation

Recalculate for an reStruct Object


The log-likelihood, or restricted log-likelihood, of the Gaussian linear mixed-effects model represented by object and conLin (assuming spherical within-group covariance structure), evaluated at coef(object) is calculated and added to the logLik component of conLin. The settings attribute of object determines whether the log-likelihood, or the restricted log-likelihood, is to be calculated. The computational methods for the (restricted) log-likelihood calculations are described in Bates and Pinheiro (1998).


## S3 method for class 'reStruct':
recalc(object, conLin, ...)


object an object inheriting from class reStruct, representing a random effects structure and consisting of a list of pdMat objects.
conLin a 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 model.
... some methods for this generic require additional arguments. None are used in this method.


the condensed linear model with its logLik component updated.
