This module function is used to specify the components of the
forecast module in EpiSewer.
Each component can be specified using one or several helper functions (see available options below). See the documentation of the individual helper functions to adjust various settings.
Usage
model_forecast(horizon = horizon_none())Arguments
- horizon
The forecast horizon. How many days into the future should EpiSewer forecast? Note that this functionality is intended for short-term forecasts. Projections over longer horizons can be highly inaccurate. Available options: -
horizon_none()
Details
Forecasts account for the estimated variation of transmission
dynamics over time and therefore become more uncertain at longer forecast
horizons. However, it is important to keep in mind that in expectation the
model will project the current transmission dynamics to continue unchanged
(with the exception of R_estimate_ets, which can project the current
linear trend of Rt). This assumption can be violated by various factors
such as depletion of susceptible individuals, changes in behavior, or
public health interventions.
