BRugs (version 0.8-2)

summary: Summary of MCMC simulation

Description

These functions are used to calculate running means, standard deviations and quantiles.

Usage

summarySet(node)
summaryStats(node)
summaryClear(node)

Arguments

node
Character vector containing names of a variables in the model.

Value

  • summaryStats returns a data frame with columns:
  • meanmeans
  • sdstandard deviations
  • val2.5pc0.025 quantiles
  • medianmedians
  • val97.5pc0.975 quantiles
  • samplesample sizes

Details

summarySet creates monitor(s) that starts recording the running totals for node. summaryStats displays the running means, standard deviations, and 2.5%, 50% (median) and 97.5% quantiles for node. Note that these running quantiles are calculated via an approximate algorithm and should therefore be used with caution. summaryClear removes the monitor(s) calculating running totals for node. These functions are less powerful and general than the samples functions (e.g., see samplesSet), but they also require much less storage (an important consideration when many variables and/or long runs are of interest).
