Apply Solve to an reStruct Object
Usage
solve(a, b, tol)
Arguments
a
|
an object inheriting from class reStruct ,
representing a random effects structure and consisting of a list of
pdMat objects.
|
b
|
this argument is only included for consistency with the
generic function and is not used in this method function.
|
tol
|
an optional numeric value for the tolerance used in the
numerical algorithm. Defaults to 1e-7 .

Description
Solve
is applied to each pdMat
component of a
,
which results in inverting the positive-definite matrices they
represent.Value
an reStruct
object similar to a
, but with the
pdMat
components representing the inverses of the
matrices represented by the components of a
