credIntSamp | R Documentation |
Calculates a lower, upper, or two-sided credible interval from the numerical posterior CDF.
credIntSamp(theta, conf = 0.95, type = "twosided")
theta |
a sample from the posterior density |
conf |
the desired 'confidence' level |
type |
the type of interval to return, 'lower' = one sided lower bound, 'two-sided' = two - sided, or 'upper' = one sided upper bound. It is sufficient to use 'l','t' or 'u' |
This function uses linear interpolation to calculate bounds for points that may not be specified by CDF
a list containing the elements lower.bound, uppper.bound or both depending on type
## posterior is N(0,1) theta = rnorm(1000) ci=credIntSamp(theta) plot(density(theta)) abline(v=c(unlist(ci)))
