%description
A family of novel beta mixture models (BMMs) has been developed by
Majumdar et al. (2022) <arXiv:2211.01938v1> to appositely model the
beta-valued cytosine-guanine dinucleotide (CpG) sites, to objectively
identify methylation state thresholds and to identify the differentially
methylated CpG (DMC) sites using a model-based clustering approach. The
family of beta mixture models employs different parameter constraints
applicable to different study settings. The EM algorithm is used for
parameter estimation, with a novel approximation during the M-step
providing tractability and ensuring computational feasibility.
