pymc_marketing.mmm.lift_test.calculate_lift_measurements_from_curve(x_before, x_after, saturation_curve, pt=<module 'pytensor.tensor' from '/home/docs/checkouts/readthedocs.org/user_builds/pymc-marketing/envs/0.7.0/lib/python3.10/site-packages/pytensor/tensor/__init__.py'>)[source]#

Calculate the lift measurements at two spends.

Parameters:

x_beforenpt.NDArray[float]: Array of x before the change.
x_afternpt.NDArray[float]: Array of x after the change.
saturation_curveCallable[[npt.NDArray[float]], npt.NDArray[float]]: Function that takes spend and returns saturation.
pttensor module, optional. Default is pytensor.tensor.

Returns:

npt.NDArray[float]: Array of lift measurements based on a given saturation curve
