A Hybrid Sampling Approach for Imbalanced Binary and Multi-Class Data Using Clustering Analysis
IEEE Access, 2022 Unequal data distribution among different classes usually cause a class imbalance problem. Due to the class imbalance, the classification models become biased toward the majority class and misclassify the minority class.

Structural Equation Modeling: A Multidisciplinary Journal, 2016 This article describes the general time-intensive longitudinal latent class modeling framework implemented in Mplus. For each individual a latent class variable is measured at each time point and the latent class changes across time follow a Markov process (i.e., a hidden or latent Markov model), with subject-specific transition probabilities that are ...

Latent class analysis variable selection [PDF]
, 2009 We propose a method for selecting variables in latent class analysis, which is the most common model-based clustering method for discrete data. The method assesses a variable's usefulness for clustering by comparing two models, given the clustering ...

Estonia – Highly Unequal but Classless? [PDF]
Studies of Transition States and Societies, 2012 In this short essay, we try to assess the utility of class analyses for understanding the contemporary Estonian society. Erik Wright (2009) identifies three strands of class analysis: a stratification approach, a Weberian approach and a Marxist approach.
