Topic: Variance Modeling with the Mixed Effects Location Scale (MELS) Model for Ecological Momentary Assessment (EMA) Data

In studies using Mobile Health measurement modalities like Ecological Momentary Assessment (EMA), up to thirty or forty observations are often obtained for each subject, and interest frequently centers around changes in the variances, both within- and between-subjects. This presentation will focus on describing application of the mixed-effects location scale (MELS) model, in which covariates can influence the outcome mean and variances.
