How to Generate an Orthogonal Array for A/B Testing in Python

Generate a mock orthogonal array for multi-layer experiments with NumPy, ensuring balanced level combinations across experiment groups.

import numpy as np

def orthogonal_mock_layers(n_experiments: int, n_layers: int, n_levels: int) -> np.ndarray:
    """Generate an orthogonal array for multi-layer experiment design using base-level logic."""
    ortho = np.indices((n_levels,) * n_layers).reshape(n_layers, -1).T
    ortho = ortho % n_levels  # Classic…
