WebDetails. The generalized inverse Gaussian distribution has density. f ( x) = ( ψ / χ) λ 2 2 K λ ( ψ χ) x λ − 1 e − 1 2 ( χ x − 1 + ψ x) for x > 0, where K λ () is the modified Bessel function of the third kind with order λ. The generalized inverse Gaussian distribution is investigated in detail in Jnsen (1982). In probability theory and statistics, the inverse gamma distribution is a two-parameter family of continuous probability distributions on the positive real line, which is the distribution of the reciprocal of a variable distributed according to the gamma distribution. Perhaps the chief use of the inverse gamma distribution is in Bayesian statistics, …

WebCompound Poisson distribution. In probability theory, a compound Poisson distribution is the probability distribution of the sum of a number of independent identically-distributed random variables, where the number of terms to be added is itself a Poisson-distributed variable. The result can be either a continuous or a discrete distribution .
