She covers several model selection … In statistics, a latent class model (LCM) relates a set of observed (usually discrete) multivariate variables to a set of latent variables. It is a type of latent variable model. It is called a latent class model because the latent variable is discrete. A class is characterized by a pattern of conditional probabilities that indicate the chance that variables take on certain values.

Thus, this class was the group with the lowest addiction-related risks. WitrynaTo achieve the aim of establishing categorical latent classes, one can employ the Expectation Maximization algorithm, which utilizes the full information maximum likelihood method of class extraction (Masyn, 2013) by randomly allocating people into classes and estimating a one-class solution, a two-class solution, and so on, until … p5s rating
