The posterior predictive distribution of the count in the treated group is a
Poisson-Gamma-Inverse Beta distribution
.
dpost_x
gives the density, ppost_x
the distribution function,
qpost_x
the quantile function, rpost_x
samples from the distribution,
and spost_x
gives a summary of the distribution.
Post_x
is a generic name for the functions documented.
