We conducted a simulation study to evaluate the performance of subgrouping multi-VAR across a range of factors and found that it performs well with respect to model/subgroup recovery and quality of estimates. Performance was also assessed in the context of an empirical example.

What's nice about this?
The competing penalty terms govern both the sparsity and heterogeneity of the solution. This allows for the flexible approximation of commonly encountered scenarios (e.g., minimal heterogeneity, subgroup-specific heterogeneity, etc.).

Subgrouping multi-VAR accommodates both quantitative and qualitative heterogeneity in the estimation of group-, subgroup-, and individual-level effects.
Notably, these dynamics are estimated simultaneously using a structured regularization approach.

Penalized Subgrouping of Heterogeneous Time Series
Interest in the study and analysis of dynamic processes in the social, behavioral, and health sciences has burgeoned in recent years due to the increased availability of intensive longitudinal...
We have a new preprint!
I'm excited to share recent work related to modeling multiple-subject, multivariate time series.
We extend the multi-VAR framework to allow for data-driven identification and penalized estimation of subgroup-specific dynamics.
