# Mixed effects, eight months, minmax scaling

 [← All flat growth benchmarks](/benchmarks/flat)

The same features on 256 daily rows.

## Input

[`benchmark/inputs/v1/flat-mixed-components-large.json`](https://github.com/jer-k/effect-prophet/blob/main/benchmark/inputs/v1/flat-mixed-components-large.json): 256 history rows and 64 forecast rows.

## Output

Largest difference: **4.0e-7** (< 0.0001% of the input's range).

Every forecast row from both libraries.
