merlin - a unified modelling framework for data analysis and methods development in Stata

TL;DR

merlin is a versatile and comprehensive modeling framework in Stata that can handle a wide range of statistical models, from simple regressions to complex joint models, facilitating advanced data analysis and method development.

Contribution

The paper introduces merlin, a unified framework in Stata capable of fitting diverse complex models, expanding analytical possibilities and future development.

Findings

Supports simple and complex models including joint and mixed effects models

Demonstrates broad capabilities on a single dataset

Discusses future enhancements for merlin in Stata

Abstract

merlin can do a lot of things. From simple stuff, like fitting a linear regression or a Weibull survival model, to a three-level logistic mixed effects model, or a multivariate joint model of multiple longitudinal outcomes (of different types) and a recurrent event and survival with non-linear effects...the list is rather endless. merlin can do things I haven't even thought of yet. I'll take a single dataset, and attempt to show you the full range of capabilities of merlin, and discuss some future directions for the implementation in Stata.
