This is the mixture distribution obtained by sampling a value b from a Beta distribution with shape parameters β, α and then sampling a Gamma distribution with shape a and rate ρ/b.
dGIB
gives the density, rGIB
samples from the distribution,
and summary_GIB
returns a summary of the distribution.
GIBDist
is a generic name for the functions documented.
