Transition probability matrix from an msmbayes model

Transition probability matrix from an msmbayes model

Usage

pmatrix(draws, t = 1, new_data = NULL, X = NULL, drop = TRUE)

Arguments

draws

Object returned by msmbayes.

t

prediction time or vector of prediction times

new_data

Data frame with covariate values to predict for

X

Lower-level alternative to specifying new_data, for developer use only. X is a numeric matrix formed from column-binding the covariate design matrices for each transition in turn.

drop

Only used if there are no covariates supplied in new_data. Then if drop=TRUE this returns a nstates x nstates matrix, or if drop=FALSE this returns a 3D array with first dimension ncovs=1.

Value

Array or matrix of rvar objects giving the transition probability matrix at each requested prediction time and covariate value. See qdf for notes on the rvar format.
