Boostrapped Assessment

Source: R/baQCA.R
baQCA.Rd

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

Usage

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

Arguments

mod

name of the QCA model object – the minimization of the truth table.

sim

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

all

logical, whether or not causal conditions AND outcome should be resampled (with replacement). Default set to all=TRUE.

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

This function returns a value which is the probability of a random QCA result (e.g. a result from random data) given the parameters set by the researcher in the model (configurational n threshold, consistency score threshold, etc), and a confidence interval around this value. This value is interpreted similarly to a p-value."
