Let’s first create some simulated data to demonstrate this. We’ll create an observed variable y that is normally distributed around 0 with a standard deviation of 2. y <- rnorm (n = 100, mean = 0, sd = 2)

WebLatent GOLD® is a powerful latent class and finite mixture program with a very user-friendly point-and-click interface (GUI). Two add-on options are available to extend the basic version of the program. The Advanced/Syntax add-on enables more control for advanced users via use of a Syntax command language including intuitive LG-equations™. Web1 Jan 2024 · This article reviews the assumptions needed to estimate the CACE in a single RCT and proposes a frequentist alternative for estimating the CACE in a meta-analysis, using a generalized linear latent and mixed model with SAS software (SAS Institute, Inc.). The method accounts for between-study heterogeneity using random effects.
Latent-variable methodology is used in many branches of medicine. A class of problems that naturally lend themselves to latent variables approaches are longitudinal studies where the time scale (e.g. age of participant or time since study baseline) is not synchronized with the trait being studied.
