suffnec {QCA3}R Documentation

Produces a sufficiency and necessity matrix

Description

creates a matrix of the sufficiency and necessity scores for a crisp set or fuzzy set data frame.

Usage

suffnec(x, use = c("complete", "pairwise"))
## S3 method for class 'suffnec':
print(x, digits = 3, ...)

Arguments

x For coincide, x is a dataframe of crip set or fuzzy set data, which ranges from 0 to 1.
use The method of handling missing data. "complete" means listwise deletion and "pairwise" means pairwise deletion.
digits a non-null value for 'digits' specifies the minimum number of significant digits to be printed in values.
... arguments passed to default method of print.

Details

In the terminology of set theory, if X is the sufficient condition of Y, then the score of X should be consistently less or equal than that of Y. Similarly, if X is the necessary condition of Y, then the sore of X should be consistently greater or equal than that of Y. The necessary score measures such consitency. The formulas can be found in Ragin(2006:297).

Value

A list of two matrixs of consistency score.

suff Sufficiency Scores Matrix,measuring the consistency score of 'X is sufficient condition of Y'.
nec Necessity Scores Matrix, measuring the consistency score of 'X is necessary condition of Y'.
