BSTZINB (version 2.0.1)

conv.test: convergence test for parameters in the fitted objects

Description

Conducts a test of convergence for a given parameter in the fitted objects using the posterior samples for the said parameter

Usage

conv.test(params,nchain=3,thshold=1.96)

Value

logical vector indicating whether convergence was achieved or not

Arguments

params

numeric matrix of dimension 2 (iterations x number of parameters, single chain) or 3 (iterations x number of parameters x chain, multiple chains) of posterior samples

nchain

positive integer, number of chains used to fit BSTZINB, BSTNB or BSTP

thshold

positive scalar, the threshold for testing the convergence. Defaults to 1.96

Examples

data(simdat)
y <- simdat$y
X <- cbind(simdat$V1,simdat$x)
data(county.adjacency)
data(USAcities)
IAcities <- subset(USAcities,state_id=="IA")
countyname <- unique(IAcities$county_name)
A <- get_adj_mat(county.adjacency,countyname,c("IA"))
# \donttest{
res3 <- BSTZINB(y, X, A, LinearT=TRUE, nchain=3, niter=100, nburn=20, nthin=1)
conv.test(res3$Alpha,nchain=3)
# }
