A list of tables required for health-economic simulation modeling.
Each table must either be a data.frame or data.table. All ID variables within
each table must be numeric vectors of integers.
hesim_data(strategies, patients, states = NULL, transitions = NULL)A table of treatment strategies.
Must contain the column strategy_id denoting a unique strategy. Other columns are variables
describing the characteristics of a treatment strategy.
A table of patients.
Must contain the column patient_id denoting a unique patient. The
number of rows should be equal to the number of patients in the model. The table
may also include columns for grp_id for subgroups and patient_wt specifying
the weight to apply to each patient (within a subgroup). If grp_id is
NULL, then it is assumed that there is only 1 subgroup. If patient_wt is
NULL. then each patient is given the same weight. Weights
within subgroups are normalized to sum to one.
Other columns are variables describing the characteristics of a patient.
A table of health states. Must contain the column
state_id, which denotes a unique health state. The number of rows should
be equal to the number of health states in the model. Other columns can describe the
characteristics of a health state.
A table of health state transitions. Must contain the column
transition_id, which denotes a unique transition; from, which denotes
the starting health state; and to which denotes the state that will be
transitioned to.
Returns an object of class hesim_data, which is a list of data tables for
health economic simulation modeling.
