semopy 2: A Structural Equation Modeling Package with Random Effects in Python

Understand

Structural Equation Modeling (SEM) is an umbrella term that includes numerous multivariate statistical techniques that are employed throughout a plethora of research areas, ranging from social to natural sciences.

• Until recently, SEM software was either commercial or restricted to niche languages, and the lack of SEM packages compatible with more mainstream programming languages was dire.
• To combat that, we introduced a Python package semopy 1 that surpassed other state-of-the-art software in terms of performance and estimation accuracy.
• Yet, it was lacking in functionality and its usage was burdened with unnecessary boilerplate code.
