View source: R/cases.suf.iir.R

Description

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

Usage

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

Arguments

results

An object of class "qca".

outcome

A character string with the name of the outcome in capital letters. When performing pimdata of the sufficient solution for the negated outcome one must only use the minimize() result from the sufficiency analysis of the negated outcome in the argument results. Changing the name in the argument outcome or using a tilde is not necessary.

neg.out

Logical. Should the negated outcome 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.

# Import your data. For example:

# Get the parsimonious solution:

                conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                incl.cut = .9, 
                include = "?", 					   
                details = TRUE, show.cases = TRUE)

# Get the intermediate solution:

# 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")

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

sol_nyp <- minimize(SCHF, outcome = "EXPORT", neg.out = TRUE,
                conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                incl.cut = .9, 
                include = "?", 					   
                details = TRUE, show.cases = TRUE)

# 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)
