IFconversion: Aggregation of primary data into Intuitionistic Representation

Description

The IFconversion - Aggregation of primary data into Intuitionistic Representation. Reference describing the method: Jefmański (2020) tools:::Rd_expr_doi("10.1007/978-3-030-52348-0_4")

Usage

IFconversion(
  primary,
  u = round(mean(c(min(primary[, -1], na.rm = TRUE), max(primary[, -1], na.rm =
    TRUE)))),
  u_is_neutral = TRUE
)

Value

IFconversion returns the decision matrix (m x n*3) with the values of the mi

ni and pi (three columns for each fuzzy representation), for the n criteria

Arguments

primary

dataset with object names (not aggregated) in first column

u

cut level

u_is_neutral

if exact value of variable is equal to u (cut_level) the variable is treated as neutral (TRUE) or negative (FALSE)
