These models not only provide valid causal mediation for time series data but also model the causal dynamics across time.

We quantify the difficulty of clustering data generated from a G-block covariance model in terms of cluster proximity, measured with respect to two related, but different, cluster separation metrics.

We analyze an adaptive procedure based on cross validation, and establish its convergence rate under the Frobenius norm.
