Description Usage Arguments Details Value Examples
Calculates and plots the posterior distribution of mortality count.
1 2 |
C |
Observed mortality count. Non-negative integer. |
Rstar |
ACME inverse-inflation factor R*, reported by acme.summary() as "Rstar." |
T |
The first term in recursive calculation of Rstar, from acme.summary. |
gam |
Values for highest posterior density credible interval. |
I |
Interval length, days. |
xlim |
2-element vector of plotting ranges. Default first element of 0, second element of 2 greater than maximum calculated for larger hpd. |
Mmax |
Maximimum value for which posterior probability is calculated. |
xi |
First parameter of gamma prior. Default is 1/2 for Objective prior. |
lam |
Second parameter of gamma prior. Default is 0 for Objective prior. |
ps |
Postscript message. Default empty string suppresses output. |
plotit |
Boolean to determine if plot should be created. Default is TRUE. |
Assuming a Gamma(xi, lam) on the average daily mortality rate m, this model treats the mortality M for the current period as Poisson-distributed with mean m*I. The carcass count C will include "new" carcasses with a Bi(M,T) distribution as well as "old" carcasses (if bt > 0). For derivation of resulting conditional pdf see Wolpert (2015).
The function invisibly returns a vector with input C, ACME estimate, posterior mean, and credible interval ranges. If plotit = TRUE, it also plots the posterior probabilities for values in the range of xlim, and prints a short summery including the true coverage probabilities.
The parameter plotit
should almost never be set to FALSE - if the user
desires the vector that is inivisibly returned, it is suggested to use the
wrapper function acme.table
.
