# Transition-specific parameters in a flexible parametric multi-state model

Source:`R/mstate.R`

`pars.fmsm.Rd`

List of maximum likelihood estimates of transition-specific parameters in a flexible parametric multi-state model, at given covariate values.

## Arguments

- x
A multi-state model fitted with

`flexsurvreg`

. See`msfit.flexsurvreg`

for the required form of the model and the data.`x`

can also be a list of`flexsurvreg`

models, with one component for each permitted transition in the multi-state model, as illustrated in`msfit.flexsurvreg`

.- trans
Matrix indicating allowed transitions. See

`msfit.flexsurvreg`

.- newdata
A data frame specifying the values of covariates in the fitted model, other than the transition number. See

`msfit.flexsurvreg`

.- tvar
Variable in the data representing the transition type. Not required if

`x`

is a list of models.

## Value

A list with one component for each permitted transition. Each component has one element for each parameter of the parametric distribution that generates the corresponding event in the multi-state model.
