Fftlog python
WebA log gamma continuous random variable. As an instance of the rv_continuous class, loggamma object inherits from it a collection of generic methods (see below for the full list), and completes them with details specific for this particular distribution. Notes The probability density function for loggamma is: f ( x, c) = exp ( c x − exp ( x)) Γ ( c)
