A named vector of NONMEM shrinkage estimates, or in the case of all,
a list of named vectors.
eta returns a vector of ETA shrinkages, as reported by NONMEM.
epsilon returns EPSILON shrinkage, as reported by NONMEM.
all returns both ETA and EPSILON shrinkage estimates as a list of vectors.
Arguments
x
A NONMEM output object generated using read_nm.
output
A flag specifying the shrinkage estimates to be output. Valid flag
values are eta (the default), epsilon, or all.
type
Specifies the type of shrinkage to report. Valid values are sd
(standard deviation, the default) or vr (variance, if present in the XML output).
sigdig
Specifies the number of significant digits to be provided (default=3).
est.step
Specifies which estimation step to return parameters from (default is the last).
