MultiLevelOptimalBayes

MultiLevelOptimalBayes (MLOB) R badge

MLOB is an R package for estimating between-group effects in multilevel latent variable models using an optimally regularized Bayesian estimator. It is especially useful for small-sample settings, low ICC data, and hierarchical models commonly used in psychology, education, and social sciences.


✨ Features


📦 Installation

To install the development version from GitHub:

install.packages("devtools")
devtools::install_github("MLOB-dev/MLOB")

MLOB is available on CRAN under the GPL-3 license. To install the released version:

install.packages("MLOB")

📦 View the Vignette

After installing the package, run the following to open the introductory vignette:

vignette("MultiLevelOptimalBayes-Intro")

📦 Examples

library(MultiLevelOptimalBayes)

Fit a model on the iris dataset

result <- mlob(Sepal.Length ~ Sepal.Width + Petal.Length, data = iris,
group = "Species", conf.level = 0.95)

View results

summary(result)

📦 Limitations

-The estimator assumes approximately equal group sizes. Although balancing helps, unequal sizes may still bias results.
