MixWILD - Mixed models With Intensive Longitudinal Data

Mixed-WILD is a statistical software designed to perform multilevel modeling (with mixed effects) on longitudinal experience sampling data. Analysing intensive longitudinal data from EMA is a challenging task and the currently available desktop applications are often insufficient for this purpose. Using Mix-WILD, behavioral researchers with no background in programming (e.g., R) can perform complex modeling on personal health data.
