rolling {ConsReg}

rolling: Back-test your model

Description

Function for creating rolling density forecast from ConsRegArima models with option for refitting every n periods.

Usage

rolling(object, used.sample, refit, h = 1, orig.data, ...)

Arguments

object

ConsRegArima object

used.sample

The starting point in the dataset from which to initialize the rolling forecast.

refit

Determines every how many periods the model is re-estimated. If refit=0, then no refit is doing

h

The number of periods to forecast

orig.data

data original which was used to estimate the ConsRegArima object

...

Additional params for predict function

Value

results

data.frame with Real, Prediction, Prediction_High, Prediction_Low and fitted values of the object

refitT

how many periods the model is re-estimated

metrics

Main metrics of the predictions
