# Preprint announcement: 'Trimmed Harrell-Davis quantile estimator based on the highest density interval of the given width'

**Update: the final paper was published in Communications in Statistics - Simulation and Computation (DOI: 10.1080/03610918.2022.2050396).**

Since the beginning of this year, I have been working on building a quantile estimator that provides an optimal trade-off between statistical efficiency and robustness. Finally, I have built such an estimator. A paper preprint is available on arXiv: arXiv:2111.11776 [stat.ME]. The paper source code is available on GitHub: AndreyAkinshin/paper-thdqe. You can cite it as follows:
