calculateMASEs: Mean Absolute Scaled Error(MASEs)
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 MASEs for the given data, diferent horizons and methods, the second one contains ranked list of the methods according to MASEs. Also the function plots MASEs for different hirizons and methods.

1	calculateMASEs(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 named "series_id" and "value").
`sort`	logical. If TRUE the resulting list of MASEs dataframe and ranked dataframe of MASEs sorting by average value.

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