Description

Backtest measures for Dynamic Model Averaging and comparison with Dynamic Model Selection. This function evaluates the out of sample performance of DMA and compare it with DMS.

Usage

1
    BacktestDMA(object, iBurnPeriod = NULL)

Arguments

object

an object of the class DMA-class, created using the function DMA.

iBurnPeriod

An integer indicating the length of the burn-in period. By default iBurnPeriod = NULL. If iBurnPeriod = NULL then one third of the total sample is used as the burn-in in period and a warning is printed.

Details

The function returns a matrix with Mean Squared Error (MSE), Mean Absolute Error (MAD) and Predictive Likelihood for DMA and DMS using the predictions during the out-of-sample period.

Value

An object of the class matrix.
