Disease progression object
Description
An object of class disprog returned from methods
$sim_disease() in model classes. It contains simulated trajectories
through a multi-state model.
Components
A disprog object inherits from data.table and contains
the following columns:
- sample
A random sample from the PSA.
- strategy_id
The treatment strategy ID.
- patient_id
The patient ID.
- from
The health state ID transitioned from.
- to
The health state ID transitioned to.
- final
An indicator equal to 1 if a patient is in their final health state during the simulation and 0 otherwise.
- time_start
The time at the start of the interval.
- time_stop
The time at the end of the interval.
The object also contains size and absorbing attributes.
The size attribute is a numeric vector with the elements n_samples,
n_strategies, n_patients, and n_states denoting the number of samples,
treatment strategies, patients, and health states The absorbing attribute
is a numeric vector containing the absorbing health states; i.e., the
health states that cannot be transitioned from. Operationally, an
absorbing state is a row in a transition matrix (as in the trans_mat field
of the IndivCtstmTrans class) with all NAs.

A disease progression object can be simulated with either the
IndivCtstm or IndivCtstmTrans classes.
