Open-source R packages for structural equation modeling and business analytics.

SEMinR

CRAN Co-Creator

A Domain-Specific Language for Building and Estimating Structural Equation Models in R. SEMinR provides an intuitive, natural syntax that lets researchers express PLS and CBSEM models using familiar terminology.

# Define structural model

Congruence Test

Web App Runs in your browser

An interactive tool for the bootstrapped congruence-coefficient test (Franke, Sarstedt & Danks, 2021, Journal of Business Research). Paste your construct scores and rho_A reliabilities to test whether pairs of constructs are empirically distinguishable in their nomological networks — no R and no install, and your data never leaves your browser. Optionally add an HTMT matrix to compare disattenuated congruence coefficients.
