baQCA {braQCA}

Boostrapped Assessment

Description

This function performs the the Bootstrapped Assessment for QCA (baQCA) on a given QCA model object.

Usage

baQCA(
  mod,
  sim = 2000,
  include = c(""),
  row.dom = FALSE,
  omit = c(),
  dir.exp = c()
)

Arguments

mod

name of the QCA eqmcc/minimize model object.

sim

the number of simulations the baQCA function should run. Default set to sim=2000.

include

[from QCA package] “A vector of additional output function values to be included in the minimization.” Default set to include=c("").

row.dom

[from QCA package] “Logical, impose row dominance as constraint on solution to eliminate dominated inessential prime implicants.” Default set to FALSE.

omit

[from QCA package] “A vector of configuration index values or matrix of configurations to be omitted from minimization.” Default set to omit=c().

dir.exp

[from QCA package] “A vector of directional expectations for deriving intermediate solutions.” Default set to dir.exp=c().

Value

After some time, this function returns the probability that the data will return a random result given the parameters set by the researcher in the model (configurational n threshold, consistency score threshold, etc), as well a confidence interval around this value. This value is interpreted similarly to a p-value, i.e. a .05 value coincides with a 95% "confidence level."

Examples

qca.data <- rallies[,8:13]
rownames(qca.data)<-rownames(rallies)
truth<-QCA::truthTable(qca.data,outcome="P",sort.by="incl",incl.cut1=0.85,n.cut=1,show.cases=TRUE)
mod1 <- QCA::minimize(truth,details=TRUE,show.cases=TRUE)

baQCA(mod1,sim=1)
