The density()
, mean()
, and variance()
methods are approximate as
they are based on numerical derivatives.
dist_transformed(dist, transform, inverse)
A univariate distribution vector.
A function used to transform the distribution. This transformation should be monotonic over appropriate domain.
The inverse of the transform
function.
