sigmoid_saturation#
- pymc_marketing.mmm.utils.sigmoid_saturation(x, alpha, lam)[source]#
Sigmoid saturation function.
- Parameters:
- x
floatornp.ndarray The input value for which the function is to be computed.
- alpha
floatornp.ndarray α (alpha): Represent the Asymptotic Maximum or Ceiling Value.
- lam
floatornp.ndarray λ (lambda): affects how quickly the function approaches its upper and lower asymptotes. A higher value of lam makes the curve steeper, while a lower value makes it more gradual.
- x
