Construction of truthTable from fuzzy set score

Description

Constructing a truthTable from fuzzy set score. This truthTable is an object of class tt, which can be passed to procedure eqmcc to get the boolean minimization.

Usage

fs_tt(mydata, outcome = "", conditions = c(""),ncases_cutoff = 1,
      consistency_cutoff = 0.8, complete= FALSE, show.cases = TRUE,
      quiet =FALSE, cases =NULL)

Arguments

mydata A fuzzy set score dataset. All the scores must range from 0 to 1.
outcome the name of the outcome variable in the dataset.
conditions the name of the conditions from the dataset.
ncases_cutoff When number of case is less than cutoff, it will be regarded as dontcare configuration.
consistency_cutoff Cutoff point of consistenty score, cases with consistency score greater than cutoff point are regarded as OUT=1.
complete prints the complete truth table, including the missing combinations
show.cases show the rownames from the original dataset for each combination of conditions.
quiet Not used currently.
cases name of cases from dataset. If it is NULL and show.cases is TRUE, name of cases are derived from row names of dataset.

Details

See fs_truthTable for more details.

Value

An object of class "truthTable". refer to truthTable for more details.
