Latest release: v2.3.0
Latest publication: Crowther MJ. merlin – a unified framework for data analysis and methods development in Stata. The Stata Journal 2020;20(4):763-784.
merlin stands for Mixed Effects Regression for LInear, Non-linear and user-defined models.
merlin has the capabilities to fit a linear regression or a Weibull survival model, 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.
The latest stable version of
merlin is available on the Statistical Software Components archive, and can be installed directly in Stata by typing:
ssc install merlin
Once installed, you can pick up any updates by typing:
merlin has the capability to fit a broad range of models, it can mean that the syntax can be tricky. To provide a more user-friendly way of accessing
merlin‘s power, we have developed a range of wrapper functions, which provide a much simpler syntax for specific classes of models.
Survival analysis made easy
Multilevel mixed effects parametric survival models
