Unlocking the World of SEM, CFA, and Path Modeling

Welcome to my bimonthly blog dedicated to delving into the intricacies of structural equation modeling (SEM), confirmatory factor analysis (CFA), and path modeling. Within these pages, you'll find posts covering crucial aspects of SEM and CFA, applicable across various modeling platforms. Additionally, I'll provide guidance on implementing models using specific software, with a special focus on R/lavaan.

I'm Arndt Regorz and I am a statistics consultant specializing in offering support to students undertaking doctoral dissertations or master's theses. The main focus of my consultant's work is SEM/CFA and multilevel modeling. My academic background includes degrees in psychology (BSc. and MSc.) and business administration. I extend my services globally with clients in Europe, America, Asia, and Australia. Whether you're based on a different continent or nearby, you can book a video consultation with me in English or in German.
