Maximum and minimum diagnostic values

Convenience function to quickly extract maximum and mininum diagnostics values of the function diagnostics.summary() over all parameters. The maximum values of the PSRF should be below 1.1 while the minumum ESS should be above 10,000. If either of this is not the case, consider to increase the length of the chains, i. e. the number of iterations.

Usage

diagnostics.max.min(x)

Arguments

x

output from function diagnostics.summary()

Value

A data.frame with one row and the following numeric columns:

• PSRF_max Maximum value of the potential scale reduction factor.

• PSRF_upper_max Mximum value of the upper limit of the 0.95-confidence interval of the PSRF.

• ESS_min Minimum of the effective sample size.

Examples

if (FALSE) { # interactive()
# select Sorsum data with auricular surface after Lovejoy et al. 1985
sorsum <- sorsum_as[,2]

# example with default settings, please be atient
sorsum_res <- bay.ta(method = sorsum)

# compute diagnostics of the MCMC samples
sorsum_diag <- diagnostic.summary(sorsum_res)

# show maximum and minimum values
diagnostics.max.min(sorsum_diag)
}
