logDet(object, covariate)
object
|
an object inheriting from class corStruct ,
representing a correlation structure.
|
covariate
|
an optional covariate vector (matrix), or list of
covariate vectors (matrices), at which values the correlation matrix,
or list of correlation matrices, are to be evaluated. Defaults to
getCovariate{object} .
