rugarch (version 1.5-3)

uGARCHroll-class: class: Univariate GARCH Rolling Forecast Class

Description

Class for the univariate GARCH rolling forecast.

Arguments

Slots

forecast:

Object of class "vector"

model:

Object of class "vector"

Extends

Class "GARCHroll", directly. Class "rGARCH", by class "GARCHroll", distance 2.

Methods

as.data.frame

signature(x = "uGARCHroll"): Extracts various values from object (see note).

plot

signature(x = "uGARCHroll", y = "missing"): Roll result backtest plots (see note).

report

signature(object = "uGARCHroll"): Roll backtest reports (see note).

resume

signature(object = "uGARCHroll"): Resumes a rolling backtest which has non-converged windows using alternative solver and control parameters.

fpm

signature(object = "uGARCHroll"): Forecast performance measures.

coef

signature(object = "uGARCHroll"): Extracts the list of coefficients for each estimated window in the rolling backtest.

quantile

signature(x = "uGARCHroll"): Calculates and returns, given a vector of probabilities (additional argument “probs”), the conditional quantiles of the rolling object as an xts matrix.

pit

signature(object = "uGARCHroll"): Calculates and returns the conditional probability integral transform given the realized data and forecast density.

convergence

signature(object = "uGARCHroll"): Returns the convergence code for the estimation windows, with 0 indicating that all have converged and 1 that there were non-converged windows. In the latter case the ‘nonconverged’ attribute is also printed of those windows which failed to converge.

show

signature(object = "uGARCHroll"): Summary.
