Helpful tips and tricks for various R commands/functions that I have found to be useful (or ones that I find myself googling all too often). I hope to continue updating this over time, but for now, hopefully this will be useful for people when doing basic analyses!

An overview of measurement invariance testing in Lavaan/SemTools.

Features usage of both Lavaan and the multicon package in R to explore McDonald's Correlated Uniqueness model, and Multi-Trait Multiple Method approaches. Omega reliability is also discussed.

An intro to using Lavaan plus how to run CFA's and other hierarchical latent variable models.

Differential prediction using the steps provided by Mendoza & Lautenschlager (1986).

This module uses the psych package primarily to explore different rotations and output produced from exploratory factor analysis.

Uses Lavaan and the Psych package to go over syntax for a higher-order, bifactor, and schmid-leiman model. Measurement invariance testing is also touched upon.

Mediation and path analysis using lavaan.

A brief into to mixed effects modeling in R using lme4.

This unit covered different approaches to the MIMIC model (all in Lavaan).

In this unit we covered RM ANOVA and Latent Growth Modeling. Packages used are the 'psych' and 'ez' packages.
