%description
Algorithms for computing and generating plots with and without error bars
for Bayesian cluster validity index (BCVI) (O. Preedasawakul, and N.
Wiroonsri, A Bayesian Cluster Validity Index, Computational Statistics &
Data Analysis, 202, 108053, 2025. <doi:10.1016/j.csda.2024.108053>) based
on several underlying cluster validity indexes (CVIs) including
Calinski-Harabasz, Chou-Su-Lai, Davies-Bouldin, Dunn,
Pakhira-Bandyopadhyay-Maulik, Point biserial correlation, the score
function, Starczewski, and Wiroonsri indices for hard clustering, and
Correlation Cluster Validity, the generalized C, HF, KWON, KWON2, Modified
Pakhira-Bandyopadhyay-Maulik, Pakhira-Bandyopadhyay-Maulik, Tang,
Wiroonsri-Preedasawakul, Wu-Li, and Xie-Beni indices for soft clustering.
The package is compatible with K-means, fuzzy C means, EM clustering, and
hierarchical clustering (single, average, and complete linkage). Though
BCVI is compatible with any underlying existing CVIs, we recommend users
to use either WI or WP as the underlying CVI.
