credBands {countSTAR}

Compute Simultaneous Credible Bands

Description

Compute (1-alpha)% credible BANDS for a function based on MCMC samples using Crainiceanu et al. (2007)

Usage

credBands(sampFuns, alpha = 0.05)

Arguments

sampFuns

Nsims x m matrix of Nsims MCMC samples and m points along the curve

alpha

confidence level

Value

m x 2 matrix of credible bands; the first column is the lower band, the second is the upper band

Note

The input needs not be curves: the simultaneous credible "bands" may be computed for vectors. The resulting credible intervals will provide joint coverage at the (1-alpha) level across all components of the vector.
