Description Usage Arguments Value Author(s) References See Also Examples

This function calculates and returns list of two dataframes, where the first data frame contains PB_MAEs for the given data, diferent horizons and methods, the second one contains ranked list of the methods according to PB_MAEs. Also the function plots PB_MAEs for different hirizons and methods.

1	calculatePB_MAEs(frame, frame2, sort = FALSE)

`frame`	A data frame containing columns "seies_id, actual", "forecast", "method", and "horizon".
`frame2`	A data frame containing observations of each time series (containing columns "series_id" and "value").
`sort`	logical. If TRUE the resulting list of MSEs dataframe and ranked dataframe of MSEs sorting by average value.
