cts-gimme doesn't always win. The discrete-time S-GIMME outperforms cts-gimme when clustering on large effect sizes (i.e., a lag-1 equivalent of ~0.60) combined with slow sampling rates due to its direct modeling of the shocks. tl;dr: think more deeply about the time-scales of your processes.

In our cts-gimme work, we highlight an issue with discrete-time models. Namely, observed effects are dependent on sampling rate. Then, if you cluster on those effects, your clusters may be artifacts of sampling rate rather than truth. We dub this, "illusory homogeneity".

Successfully defended my dissertation. I’m a doctor now! Got knighted by my advisors, Sy-Miin Chow and Peter Molenaar with an engraved sword gifted to my by Alexis Santos. Lots of folks to thank but never enough space in these character limits.
