Thanks for the nice blog post about our paper! I'll just add that our shrinkage estimator is a little bit ad hoc, but we did evaluate its performance: onlinelibrary.wiley.com/doi/full/10....
Evaluating a shrinkage estimator for the treatment effect in clinical trials
The main objective of most clinical trials is to estimate the effect of some treatment compared to a control condition. We define the signal-to-noise ratio (SNR) as the ratio of the true treatment ef...
