Initialize corStruct Object
This method initializes
object by evaluating its associated
covariate(s) and grouping factor, if any is present, in
calculating various dimensions and constants used by optimization
corStruct objects (see the appropriate
Dim method documentation), and assigning initial values for
the coefficients in
object, if none were present.
## S3 method for class 'corStruct': Initialize(object, data, \dots)
an initialized object with the same class as
representing a correlation structure.
