Overview

Randomized trial compares structural equation modelling tools in R, suggesting tailored choices based on research goals.

Key Points

  • This research aims to compare the lavaan and seminr packages for structural equation modelling, assessing their applicability based on research goals.
  • Used an identical model for SEM with both lavaan (covariance-based) and seminr (variance-based).
  • Compared outputs in terms of model specification, evaluation criteria, and reporting conventions.
  • Demonstrated practical applications rather than theoretical comparisons.
  • Both lavaan and seminr yield similar conclusions regarding relationships between constructs.
  • Lavaan provides richer model-fit diagnostics, while seminr emphasizes predictive assessment and latent variable scores.
  • Choice of SEM tool should align with the research objective, favoring lavaan for theory testing and seminr for prediction.
