EBMApredict {EBMAforecast}R Documentation

EBMApredict

Description

Function allows users to create new predictions given an already estimated EBMA model This function produces predictions based on EBMA model weights and component model predictions.

Usage

EBMApredict(EBMAmodel, Predictions, Outcome = NULL, ...)

## S4 method for signature 'ForecastData'
EBMApredict(EBMAmodel, Predictions, Outcome = NULL, ...)

Arguments

EBMAmodel

An estimated EBMA model object

Predictions

A matrix with a column for each component model's predictions.

Outcome

An optional vector containing the true values of the dependent variable for all observations in the test period.

...

Not implemented

Value

Returns a data of class 'FDatFitLogit' or FDatFitNormal, a subclass of 'ForecastData', with the following slots:

predTest

A matrix containing the predictions of all component models and the EBMA model for all observations in the test period.

period

The period, "calibration" or "test", for which the statistics were calculated.

outcomeTest

An optional vector containing the true values of the dependent variable for all observations in the test period.

modelNames

A character vector containing the names of all component models. If no model names are specified, names will be assigned automatically.

modelWeights

A vector containing the model weights assigned to each model.
