Description

A function that matches typical cases and individually irrelevant cases with regards to sufficiency for each INUS condition.

Usage

1
2
matches.suf.typiir(results, outcome, term = 1, neg.out=FALSE, 
                  sol=1, max_pairs = 5)

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.

term

A numeric vector where the first number indicates the number of the term according to the order in the "qca" object.

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.

max_pairs

Maximum number of pairs to extract.

# Import your data. For example:

data(SCHF)

# Get the parsimonious solution:


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


# Match typical cases and individually irrelevant cases for each conjunct 
# for the first term (default) of the parsimonious solution and return only the best 3 pairs:

matches.suf.typiir(results = sol_yp, outcome = "EXPORT", max_pairs=2)

# 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)

# Match typical cases and individually irrelevant cases for each conjunct for 
# the first term of the second parsimonious solution for the absence of the outcome:

matches.suf.typiir(results = sol_nyp, outcome = "EXPORT", neg.out = TRUE, term = 1, sol = 2)

# since it has only one condition, it cannot find pairs based on the INUS principle!
