draw_incident_population {rprev}

Simulates an incident population according to a specific incidence model

Description

This method defines the main behaviour of an incidence model and must be implemented for any class to be used in prevalence.

Usage

draw_incident_population(object, data, timeframe, covars)

Arguments

object

The incidence model.

data

The original registry data frame passed into prevalence. It is supplied in this method so that individual level attributes can be sampled from the prior distribution.

timeframe

The amount of time in days in which to simulate incidence for.

covars

Any patient level covariates that must be included in the new simulated incident population, as a character vector. These will correspond to columns in data.

Value

A data frame where each row corresponds to a simulate incident patient. The first column must be incidence time (in days). This will be relative to an unspecified baseline. All covariates specified in covars must be present in this data frame.
