A list representing the model for covariates on transition intensities
Number of covariate effect parameters. This is defined as the number of covariates on intensities (with factors expanded as contrasts) multiplied by the number of allowed transitions in the model.
Note if
msm
was called with covariates
set to a list of
different covariates for different intensities, then this will
include covariate effects that are implicitly defined as zero by
this list. The information in
paramdata
objects
can be used to identify wich ones are fixed at zero.
This also includes any timeperiod
covariates in a
time-inhomogeneous model defined by the pci
option to msm
.
Number of distinct covariate effect parameters, as
npars
, but after any equality constraints have been applied.
Number of covariates on intensities, with factors expanded as contrasts.
List of equality constraints on these covariate effects,
as supplied in the constraint
argument to msm
.
Names / labels of these covariates in the model
matrix (see model.matrix.msm
).
Initial values for these covariate effects, as a vector
formed from the covinits
list supplied to msm
.
Means of these covariates in the data (excluding data not required to fit the model, such as observations with missing data in other elements or subjects' last observations). This includes means of 0/1 factor contrasts as well as continuous covariates (for historic reasons, which may not be sensible).
