Country, custom events and mixed features

match ← All flat growth benchmarks

96 days with US country holidays, custom events, conditional weekly seasonality and a promotion regressor. Holiday effects are multiplicative.

Input

benchmark/inputs/v5/country-mixed-96.json: 96 history rows and 4 forecast rows.

Output

Largest difference: 3.0e-5 (0.00062% of the input's range).

Every forecast row from both libraries.
