The practical guide behind this tool: when it applies, how to read the output, and the traps that make it say the wrong thing.
Standard-library analysis: how good are the forecasts you already made? Map the period, the forecast, and the actual outcome (and optionally the horizon each forecast was made at) and get the full scorecard: MAE and RMSE in your own units, MAPE with its zero and asymmetry traps handled explicitly, sMAPE, MASE against both the naive and the seasonal-naive baseline, bias as a mean error plus the share of periods over- and under-forecast, a Diebold-Mariano test of whether the forecast really beats a baseline rather than just printing two numbers next to each other, actual against forecast over time, the error distribution, and accuracy broken out by calendar period and by forecast horizon.
