## updatepars.msm

### Description

Update the maximum likelihood estimates in a fitted model object. Developer use only.

### Usage

    updatepars.msm(x, pars)

### Arguments

`x` | A fitted multi-state model object, as returned by `msm`.
`pars` | Vector of new parameters, in their untransformed real-line parameterisations, to substitute for the maximum likelihood estimates corresponding to those in the `estimates` component of the fitted model object (`msm.object`). The order of the parameters is documented in `msm`, argument `fixedpars`.

### Value

An updated `msm` model object with the updated maximum likelihood estimates, but with the covariances / standard errors unchanged.

Point estimates from output functions such as `qmatrix.msm`, `pmatrix.msm`, or any related function, can then be evaluated with the new parameters, and at arbitrary covariate values.

This function is used, for example, when computing confidence intervals from `pmatrix.msm`, and related functions, using the `ci="normal"` method.
