AsymmetricGaussianBasis

class pymc_marketing.mmm.events.AsymmetricGaussianBasis(event_in='after', **kwargs)

Asymmetric Gaussian bump basis transformation.

Allows different widths (sigma_before, sigma_after) and amplitudes (a_after) after the event.

(Source code, png, hires.png, pdf)

Parameters:

event_inLiteral[“before”, “after”, “exclude”]

Whether to include the event in the before or after part of the basis, or leave it out entirely. Default is “after”.

priorsdict[str, Prior]

Prior for the sigma_before, sigma_after, a_before, and a_after parameters.

prefixstr

Prefix for the parameters.
