tpmatrix_id: Transition probability matrix IDs

In hesim: Health Economic Simulation Modeling and Decision Analysis

Transition probability matrix IDs

Description

Creates ID variables for each row returned by tpmatrix(). This function is most conveniently used along with tpmatrix() to construct a tparams_transprobs() object.

Usage

tpmatrix_id(object, n_samples)

Arguments

object	An object of class expanded_hesim_data returned by expand.hesim_data(). This dataset must be expanded by treatment strategies, patients, and optionally time intervals.
n_samples	The number of parameters samples used for the probabilistic sensitivity analysis (PSA).

Value

Returns a tpmatrix_id object that inherits from data.table with the same columns in object repeated n_samples times. That is, to facilitate creation of a tparams_transprobs() object, there is one row for each parameter sample, treatment strategy, patient, and optionally time interval.

Examples

strategies <- data.frame(strategy_id = c(1, 2))
patients <- data.frame(patient_id = seq(1, 3), age = c(65, 50, 75),
                        gender = c("Female", "Female", "Male"))
hesim_dat <- hesim_data(strategies = strategies,
                        patients = patients)
input_data <- expand(hesim_dat, by = c("strategies", "patients"))    
tpmatrix_id(input_data, n_samples = 2)
