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)

## Arguments

strategies |
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. |

patients |
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. |

states |
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. |

transitions |
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. |

## Value

Returns an object of class `hesim_data`

, which is a list of data tables for
health economic simulation modeling.
