\title{Predictions of identified model}
\usage{
\method{predict}{estpoly}(x, newdata = NULL, nahead = 1)
}
\arguments{
\item{x}{\code{estpoly} object containing the identified model}
\item{newdata}{optional dataset to be used for predictions. If not supplied,
predictions are made on the training set.}
\item{nahead}{number of steps ahead at which to predict (Default:1). For infinite-
step ahead predictions or pure simulation, supply \code{Inf}.}
}
\value{
Time-series containing the predictions
}
\description{
Predicts the output of an identified model (\code{estpoly}) object K steps ahead.
}
\examples{
data(arxsim)
mod1 <- oe(arxsim,c(2,1,1))
Yhat <- predict(mod1,arxsim) # 1-step ahead predictions
Yhat_2 <- predict(mod1,arxsim,nahead=2) # 2-step ahead predictions
Yhat_inf <- predict(mod1,arxsim,nahead=Inf) # Infinite-step ahead predictions
