An object giving information about the parameters of the multistate
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. 
plabs 
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.

Indices of parameters in

Indices of "auxiliary" parameters which are always fixed,

Vector of integers, of length 
npars 
Total number of parameters, equal to

Number of fixed parameters, equal to 
nopt 
Number of parameters being estimated, equal to

ndup 
Number of parameters defined as duplicates of previous parameters by equality constraints (currently unused). 
ranges 
Matrix of defined ranges for each parameter on the natural scale (e.g. 0 to infinity for rate parameters). 
opt 
Object returned by the optimisation routine (such as

Minus twice the log likelihood at the parameter estimates.

Derivatives of the minus twice log likelihood at the parameter estimates, if available.

Corresponding expected information matrix at the parameter estimates, if available.
