effectiveSize.dmc: Effective Sample Size for Estimating the Mean

In TasCL/ggdmc: Dynamic Model of Choice with Parallel Computation, and C++ Capabilities

Description

effectiveSize.dmc calls coda effectiveSize to effective size for either single or multiple subjects. It can calculate at the data or hyper level, too.

Usage

effectiveSize.dmc(x, hyper = FALSE, digits = 0, start = 1, end = NA)

Arguments

x	a DMC sample
hyper	a switch to extract hyper attribute and calculate it
digits	print out how many digits
start	start iteration
end	end iteraton
