WebJul 19, 2024 · Cannon (2024) considered non-crossing nonlinear regression quantiles by CQRNN; Jiang et al. (2024) added ANN to expectile regression similar to QRNN. As a nonlinear QR, QRNN is believed to guarantee the flexibility and a good performance in forecasting, but it fails in interpretability.
