cases.suf.iir: List individually irrelevant cases for sufficiency.

Description

A function that extracts individually irrelevant cases for sufficiency from an object of class "qca".

Usage

cases.suf.iir(results, outcome, neg.out=FALSE, intermed=FALSE, sol = 1)

Arguments

results

An object of class "qca".

outcome

A character string with the name of the outcome.

neg.out

Logical. Should the negated outcome be used?

intermed

Logical. Should the intermediate solution be used?

sol

A numeric vector where the first number indicates the number of the solution in case of model ambiguity according to the order in the "qca" object.

# Return individually irrelevant cases for sufficiency for the parsimonious solution:

cases.suf.iir(results = sol_yp, outcome = "EXPORT")

# Return individually irrelevant cases cases for sufficiency for the intermediate solution:

cases.suf.iir(results = sol_yi, outcome = "EXPORT", intermed = TRUE)

# Get the parsimonious solution for the absence of the outcome:

# Return individually irrelevant cases for sufficiency for the second parsimonious solution 
# for the absence of the outcome:

cases.suf.iir(results = sol_nyp, outcome = "EXPORT", neg.out = TRUE, sol = 2)
