"mselm".

a numeric vector (for selm-class objects) or a matrix
(for mselm-class objects).
The possible options of param.type are described in the
documentation of dp2cp; their corresponding outcomes
differ by an additive constant only. With the "CP" option (that is,
the ‘centred parametrization’), the residuals are centred around 0,
at least approximately; this is a reason for setting "CP" as the
default option. For more information, see the ‘Note’ in the
documentation of summary.selm.
