Bayesian estimator for the Birnbaum-Saunders family under progressive type-II censoring scheme.
Description
Estimates parameters of the Birnbaum-Saunders family in a Bayesian framework through the Metropolis-Hasting algorithm when subjects are placed on progressive type-II censoring scheme with likelihood function
in which is cumulative distribution function of the Birnbaum-Saunders family with
. The acceptance for each new sample of
and
, respectively, becomes
,
Usage
typeIIbs(plan, M0 = 4000, M = 6000, CI = 0.95)
Arguments
plan |
Censoring plan for progressive type-II censoring scheme. It must be given as a |
M0 |
The number of sampler runs considered as burn-in. |
M |
The number of total sampler runs. |
CI |
Confidence or coverage level for constructing percentile confidence interval. That is 0.95 by default. |
Value
A list including summary statistics after burn-in point including: mean, median, standard deviation, 100(1 - CI
)/2 percentile, 100(1/2 + CI
/2) percentile.
