RDA merlin

A unified framework for methods development and data analysis

merlin stands for Mixed Effects Regression for LInear, Non-linear and user-defined models (Crowther, 2020).

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.
