Function mase

mase(
    actual: Float32Array,
    predicted: Float32Array,
    naiveForecast: Float32Array,
): number
Mean Absolute Scaled Error.

MASE = MAE(model) / MAE(naive)

Values < 1 indicate the model outperforms the naive (no-change) forecast.
Parameters
- actual: Float32Array
- predicted: Float32Array
- naiveForecast: Float32Array
Returns number
