摘要：
The kernel density estimation is a popular method in density estimation. The main issue is bandwidth selection, which is a well-known topic and is still frustrating statisticians. A robust least squares cross-validation bandwidth is proposed, which significantly improves the classical least squares cross-validation bandwidth for its variability and undersmoothing, adapts to different kinds of densities, and outperforms the existing bandwidths in statistical literature and software.
