Advances in Latent Variable Mixture Models by Gregory R. Hancock

By Gregory R. Hancock

The present quantity, Advances in Latent Variable combination versions, comprises chapters by way of the entire audio system who participated within the 2006 CILVR convention, supplying not only a photograph of the development, yet extra importantly chronicling the state-of-the-art in latent variable combination version learn. the amount begins with an summary bankruptcy by means of the CILVR convention keynote speaker, Bengt Muthén, providing a "lay of the land" for latent variable blend types earlier than the amount strikes to extra particular constellations of issues. half I, Multilevel and Longitudinal structures, offers with combinations for info which are hierarchical in nature both because of the data's sampling constitution or to the repetition of measures (of diverse varieties) through the years. half II, types for evaluation and analysis, addresses eventualities for making judgments approximately contributors' kingdom of information or improvement, and concerning the tools used for making such judgments. ultimately, half III, demanding situations in version review, makes a speciality of many of the methodological concerns linked to the choice of types so much effectively representing the procedures and populations lower than research. it's going to be acknowledged that this quantity isn't really meant to be a primary publicity to latent variable equipment. Readers missing such foundational wisdom are inspired to refer to fundamental and/or secondary didactic assets with a view to get the main from the chapters during this quantity. as soon as armed with that simple knowing of latent variable equipment, we think readers will locate this quantity exceptionally intriguing.

For simplicity, we estimate the restricted FMA model where the factor loadings λjc are class invariant, λjc = λi. 6 shows the log-likelihood values and the number of parameters for the two-class LCA, FMA, and FMA-GoM models. In this example, the FMA improved the likelihood dramatically over the LCA model, however the FMA-GoM improved the likelihood only marginally. 86. Thus, in this example the concept of partial class membership is not supported by the data. The substantive conclusion appears to be that individuals are never in a transitional phase and are preset to be in one of the two classes.
