Forecasts `h`

steps ahead with a BATS model. Prediction intervals are
also produced.

# S3 method for bats
forecast(object, h, level = c(80, 95), fan = FALSE,
biasadj = NULL, ...)
# S3 method for tbats
forecast(object, h, level = c(80, 95), fan = FALSE,
biasadj = NULL, ...)

## Arguments

object |
An object of class "`bats` ". Usually the result of a call
to `bats` . |

h |
Number of periods for forecasting. Default value is twice the
largest seasonal period (for seasonal data) or ten (for non-seasonal data). |

level |
Confidence level for prediction intervals. |

fan |
If TRUE, level is set to `seq(51,99,by=3)` . This is suitable
for fan plots. |

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, currently ignored. |

## Value

An object of class "`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.bats`

.

An object of class `"forecast"`

is a list containing at least the
following elements:

modelA copy of the `bats`

object

methodThe name of the forecasting method as a character string

meanPoint forecasts as a time series

lowerLower limits for
prediction intervals

upperUpper limits for prediction intervals

levelThe confidence values associated with the prediction intervals

xThe original time series (either `object`

itself or the time
series used to create the model stored as `object`

).

residualsResiduals from the fitted model.

fittedFitted
values (one-step forecasts)
