In svcuonghvktqs/FORA: A package for time sereis forecast accuracy evaluation

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 MAEs for the given data, diferent horizons and methods, the second one contains ranked list of the methods according to MAEs. Also the function plots MAEs for different hirizons and methods.

1	calculateMAEs(frame, sort = FALSE)

`frame`	A data frame containing columns "actual", "forecast", "method", and "horizon".
`sort`	logical. If TRUE the resulting list of MAEs dataframe and ranked dataframe of MAEs sorting by average value.
