paramdata.object | R Documentation |
An object giving information about the parameters of the multi-state model.
Used internally during maximum likelihood estimation and arranging results.
Returned as the paramdata
component of a fitted msm
model object.
inits |
Vector of initial values for distinct parameters which are being estimated. These have been transformed to the real line (e.g. by log), and exclude parameters being fixed at their initial values, parameters defined to be always fixed (e.g. binomial denominators) and parameters constrained to equal previous ones. |

Names of parameters in

allinits |
Vector of parameter values before estimation, including those which are fixed or constrained to equal other parameters, and transformed to the real line. |

Number of parameters defined as duplicates of previous parameters by equality constraints (currently unused). |

Matrix of defined ranges for each parameter on the natural scale (e.g. 0 to infinity for rate parameters). |
