stateprobs

An object of class <code>stateprobs</code> returned from methods
<code>$sim_stateprobs()</code> in model classes.

A modular and computationally efficient R package for
parameterizing, simulating, and analyzing health economic simulation
models. The package supports cohort discrete time state transition models
(Briggs et al. 1998) <doi:10.2165/00019053-199813040-00003>,
N-state partitioned survival models (Glasziou et al. 1990)
<doi:10.1002/sim.4780091106>, and individual-level continuous
time state transition models (Siebert et al. 2012) <doi:10.1016/j.jval.2012.06.014>,
encompassing both Markov (time-homogeneous and time-inhomogeneous) and
semi-Markov processes. Decision uncertainty from a cost-effectiveness analysis is
quantified with standard graphical and tabular summaries of a probabilistic
sensitivity analysis (Claxton et al. 2005, Barton et al. 2008) <doi:10.1002/hec.985>,
<doi:10.1111/j.1524-4733.2008.00358.x>. Use of C++ and data.table
make individual-patient simulation, probabilistic sensitivity analysis,
and incorporation of patient heterogeneity fast.

stateprobs function

A <code>stateprobs</code> object inherits from <code>data.table</code> and contains
the following columns:<dl class="dl-horizontal">
<dt>sample</dt><dd>A random sample from the PSA.</dd>
<dt>strategy_id</dt><dd>The treatment strategy ID.</dd>
<dt>patient_id</dt><dd>The patient ID.</dd>
<dt>grp_id</dt><dd>The subgroup ID.</dd>
<dt>state_id</dt><dd>The health state ID.</dd>
<dt>t</dt><dd>The time at which a state probability is computed.</dd>
<dt>prob</dt><dd>The probability of being in a given health state.</dd>
</dl>When simulating individual-level models, the <code>patient_id</code> column is
not included as state probabilities are computed by averaging across patients.
