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.
