Latent Class Analysis is a statistically principled technique for unsupervised learning that uses a probability model to infer relationships between observed categorical data and unmeasured variables. It identifies latent classes that explain the observed patterns in the data, allowing for analysis and clas...
Synonyms Multigroup latent-class analysis Definition Simultaneous latent-class analysis across groups (SLCAG) is an extension of the standard latent-class (LC) model ( Latent Class Model ) for the examination of measurement equivalence/invariance ( Measurement Invariance ). It can be used to ...

Asthma-COPD overlap syndrome (ACOS) is an emerging concept where clinical features from both conditions co-exist, and for which, however, there is no consensus definition. Nonetheless, we expect EHR data of people with ACOS to be systematically different from those with "asthma only" or "COPD...
Furthermore, class 3 had high probability of three CHS criteria including low physical activity, slowness and weakness; this class fit the CHS frailty definition best, though the prevalence differed from that obtained using CHS criteria (15.8% by LCA vs. 6.8% in ILAS). AIC favored the three-...
Analysis: Type = Mixture; starts=0; Model: %overall% Y on X; (and so on..) I would like to regress a distal outcome on the latent class variable (C) & several covariates in Step 3. Do I need to specify the outcome & covariates in an AUXILIARY statement? Thank you very...
We propose a two-step estimator for multilevel latent class analysis (LCA) with covariates. The measurement model for observed items is estimated in its first step, and in the second step covariates are added in the model, keeping the measurement model parameters fixed. We discuss model identifi...

Results Two models yielded good fit to the data, a 2-class model with two adjustments and a 3-class model with one adjustment. The definition of latent disease associated with the latter was more stringent, backed by three of the four tests. Under that model, sensitivity for VIA (abnormal...
