Study on nonparametric transformed kernel estimate model for flood frequency analysis

By combination of the transformation theory with nonparametric statistical theory, the nonparametric transformed kernel estimate model was developed. Without requirement for selection of window width, the present model improves the precision in small sample estimation. The comparison of the estimated result by the developed model with that by the Monte-Carlo method shows that the nonparametric transformed kernel estimate model is robust.
