| logDet.reStruct {nlme} | R Documentation |
Calculates, for each of the pdMat components of object,
the logarithm of the determinant of a square-root factor.
## S3 method for class 'reStruct': logDet(object, ...)
object |
an object inheriting from class reStruct,
representing a random effects structure and consisting of a list of
pdMat objects. |
... |
some methods for this generic require additional arguments. None are used in this method. |
a vector with the log-determinants of square-root factors of the
pdMat components of object.
