From forecast v7.2
by Rob Hyndman

##### Forecasting using Structural Time Series models

Returns forecasts and other information for univariate structural time series models.

- Keywords
- ts

##### Usage

`"forecast"(object, h=ifelse(object$coef["epsilon"] > 1e-10, 2*object$xtsp[3],10), level=c(80,95), fan=FALSE, lambda=NULL, biasadj=FALSE, ...)`

##### Arguments

- object
- An object of class "
`StructTS`

". Usually the result of a call to`StructTS`

. - h
- Number of periods for forecasting
- level
- Confidence level for prediction intervals.
- fan
- If TRUE, level is set to seq(51,99,by=3). This is suitable for fan plots.
- lambda
- Box-Cox transformation parameter. Ignored if NULL. Otherwise, forecasts back-transformed via an inverse Box-Cox transformation.
- biasadj
- Use adjusted back-transformed mean for Box-Cox transformations. If TRUE, point forecasts and fitted values are mean forecast. Otherwise, these points can be considered the median of the forecast densities.
- ...
- Other arguments.

##### Details

This function calls `predict.StructTS`

and constructs an object of class "`forecast`

" from the results.

##### Value

`forecast`

".The function `summary`

is used to obtain and print a summary of the
results, while the function `plot`

produces a plot of the forecasts and prediction intervals.The generic accessor functions `fitted.values`

and `residuals`

extract useful features of
the value returned by `forecast.StructTS`

.An object of class `"forecast"`

is a list containing at least the following elements:
