B1Nsir function

Bayesian analysis of a Normal sample using a SIR prior.

This function performs a standard Bayesian analysis of a single sample of a population assumed to follow a Normal distribution. A Standard Improper Reference prior is assumed.

B1Nsir(x, r = 10000, alpha = 0.05)

Arguments

• x: a vector of sample values
• r: the number of samples to be taken from the posterior distribution (defaults to 10000)
• alpha: 1 - level of credibility, so that for alpha = 0.05 (the default) credible intervals will have 95% credibility

Returns

none returned; the function produces a plot of the posterior distribution and prints some statistics.
