  "Description": "Traditional latent variable models assume that the\npopulation is homogeneous, meaning that all individuals in the\npopulation are assumed to have the same latent structure.\nHowever, this assumption is often violated in practice given\nthat individuals may differ in their age, gender, socioeconomic\nstatus, and other factors that can affect their latent\nstructure. The robust expectation maximization (REM) algorithm\nis a statistical method for estimating the parameters of a\nlatent variable model in the presence of population\nheterogeneity as recommended by Nieser & Cochran (2023)\n<doi:10.1037/met0000413>. The REM algorithm is based on the\nexpectation-maximization (EM) algorithm, but it allows for the\ncase when all the data are generated by the assumed data\ngenerating model.",
