Hi,

The subject of my question is pretty straight forward. When to use which?

Also, why is the `pm.math.sigmoid`

defined in the docs as “Logistic sigmoid function (1 / (1 + exp(x))” while the sigmoid function is defined as (1 / (1 + exp(-x)) according to Wikipedia? And then, in the docs, the `pm.math.invlogit`

is defined with the -x in the exponent, as the sigmoid function in Wikipedia.

Thank you!
