Description

Fuzzy C-Means for Fuzzy Data.

Implements a fuzzy clustering approach for ordinal Likert-type data using triangular fuzzy numbers (TFNs). The package extends the classical fuzzy C-means algorithm to better handle uncertainty in ordinal scales and includes automatic selection of the number of clusters using the Xie-Beni validity index.

Fuzzy C-Means Clustering for Ordinal Data using Triangular Fuzzy Numbers


Overview

The fcmfd package implements fuzzy clustering for ordinal Likert-type data using Triangular Fuzzy Numbers (TFNs).

It is designed for datasets where responses are measured on discrete ordinal scales (e.g., 1-5, 1–7, 1-10 or 0–10), providing a robust alternative to traditional clustering approaches.


Features

  • Fuzzy C-Means clustering adapted to TFNs
  • Automatic selection of the optimal number of clusters
  • Xie–Beni validity index
  • Support for Likert-type data
  • Cluster assignment and prototype extraction
  • Visualization tools

Installation

# install.packages("devtools")
devtools::install_github("yourusername/fcmfd")

Example

library(fcmfd)

# Load dataset
data(sim_likert_0_10)

# Run clustering
result <- fcmTFN(
  data = sim_likert_0_10,
  option = "B",
  k_values = 2:6
)

# Summary
summary(result)

# Cluster assignment
clusters <- cluster_assignment(result)
table(clusters)

# Plot Xie–Beni index
plot_xb(result)

Included Datasets

  • sim_likert7 Simulated dataset with a 1–7 Likert scale

  • sim_likert_0_10 Simulated dataset with a 0–10 Likert scale and latent cluster structure


Methodological Background

The package combines:

  • Fuzzy C-Means clustering
  • Triangular Fuzzy Numbers representation
  • Xie–Beni cluster validity index

to provide a framework tailored for ordinal data.


Uses Cases

  • Survey analysis
  • Social sciences
  • Customer satisfaction
  • Quality of life studies
  • Likert-type data clustering
