pyhgf.math.parametrised_sigmoid

pyhgf.math.parametrised_sigmoid(x, theta, phi)

Compute the sigmoid parametrised by \(\phi\) and \(\theta\).

Parameters:

• x (Array | ndarray | bool | number | bool | int | float | complex) – The point(s) at which the sigmoid is evaluated.

• theta (Array | ndarray | bool | number | bool | int | float | complex) – The location (inflexion point) \(\theta\) of the sigmoid.

• phi (Array | ndarray | bool | number | bool | int | float | complex) – The slope \(\phi\) of the sigmoid.

Returns:

The sigmoid evaluated at x.

Return type:
