Post_y {brr} | R Documentation |
Density, distribution function, quantile function and random generation for the posterior predictive distribution of the count in the control group.

The posterior predictive distribution of the count in the treated group is a
Poisson-Gamma-Inverse Beta distribution
.
dpost_y
gives the density, ppost_y
the distribution function,
qpost_y
the quantile function, rpost_y
samples from the distribution,
and spost_y
gives a summary of the distribution.
Post_y
is a generic name for the functions documented.
