A glossy, complete therapy of latent type and latent transition research for express data
On an everyday foundation, researchers within the social, behavioral, and wellbeing and fitness sciences gather info and healthy statistical versions to the accrued empirical info with the objective of creating major advances in those fields. in lots of situations, it may be necessary to spot latent, or unobserved, subgroups in a inhabitants, the place participants' subgroup club is inferred from their responses on a collection of saw variables. Latent type and Latent Transition Analysis presents a entire and unified advent to this subject via exceptional, step by step displays and insurance of theoretical, technical, and sensible concerns in specific latent variable modeling for either cross-sectional and longitudinal data.
The ebook starts with an advent to latent category and latent transition research for specific facts. next chapters delve into extra in-depth fabric, featuring:
A entire therapy of longitudinal latent type models
Focused assurance of the conceptual underpinnings of interpretation and evaluationof a latent type solution
Use of parameter regulations and detection of id problems
Advanced themes resembling multi-group research and the modeling and interpretation of interactions among covariates
The authors current the subject in a method that's available but rigorous. each one technique is gifted with either a theoretical historical past and the sensible info that's beneficial for any information analyst. Empirical examples exhibit the real-world purposes of the mentioned recommendations and types, and every bankruptcy concludes with a "Points to recollect" part that features a short precis of key principles. the entire analyses within the e-book are played utilizing Proc LCA and Proc LTA, the authors' personal software program applications that may be run in the SAS® surroundings. A comparable site homes details on those freely to be had courses and the book's information units, encouraging readers to breed the analyses and in addition test their very own variations.
Latent category and Latent Transition Analysis is a superb booklet for classes on specific facts research and latent variable types on the upper-undergraduate and graduate degrees. it's also a beneficial source for researchers and practitioners within the social, behavioral, and overall healthiness sciences who behavior latent type and latent transition research of their daily work.
