| qmodel.object | R Documentation |
A list giving information about the structure of states and allowed
transitions in a multi-state model, and options for likelihood calculation.
Used in internal computations, and returned in a fitted msm
model object.
nstates |
Number of states |
iso |
Label for which basic
structure the model is isomorphic to in the list of structures for which
analytic formulae for the transition probabilities are implemented in the
source file
|
perm |
Permutation required to convert the base isomorphism into the structure of this model. A vector of integers whose rth element is the state number in the base structure representing state r in the current structure. |
qperm |
Inverse permutation: vector whose rth element is the state number in the current structure representing the rth state in the base structure. |
npars |
Number of allowed
instantaneous transitions, equal to |
imatrix |
Indicator matrix for allowed instantaneous transitions. This has (r,s) entry 1 if the transition from r to s is permitted in continuous time, and 0 otherwise. The diagonal entries are arbitrarily set to 0. |
qmatrix |
Matrix of initial values for the
transition intensities, supplied as the |
inits |
Vector of these initial values, reading
across rows of |
constr |
Indicators for equality constraints on baseline
intensities, taken from the |
ndpars |
Number of distinct allowed instantaneous transitions, after applying equality constraints. |
expm |
Use expm package to
calculate matrix exponentials for likelihoods, as supplied to the
|
msm.object,emodel.object,
hmodel.object.
