|
af |
dataframe containing forecast data formatted using the Actual and Forecast Table
Schema (AFTS), use |
sort |
if TRUE, sorts accuracy results according to the average SMAPE rank across all available horizons. |
digits |
number of digits after the dot used to output SMAPE; if digits=NA, SMAPEs and ranks are not rounded. |
Calculates SMAPEs for each horizon and each method contained in af
.
Outputs accuracy tables and plots.
The input dataframe af
can be created using createAFTS()
.
a list with the following variables:
dataframe with accuracy table for SMAPE
dataframe with SMAPE ranks
ggplot2 object showing accuracy vs horizon for SMAPE
