# Explicit floor with a regressor, minmax scaling

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

The same floor, regressor and weekly pattern under minmax scaling.

## Input

[`benchmark/inputs/v1/logistic-explicit-floor.json`](https://github.com/jer-k/effect-prophet/blob/main/benchmark/inputs/v1/logistic-explicit-floor.json): 96 history rows and 24 forecast rows.

## Output

Largest difference: **1.1e-11** (< 0.0001% of the input's range).

Every forecast row from both libraries.
