Generalized edge frequency polygon for density estimation


  • Dong, Jianping
  • Zheng, Chuang


Jones et al. (Biometrica 85, 235) proposed an edge frequency polygon estimator to estimate a probability density function. Their estimator has a smaller asymptotic mean integrated squared error than that of the frequency polygon estimator. In this paper we introduce a generalized edge frequency polygon estimator. Instead of averaging heights of two bins at each bin edge, we take weighted averages of the heights in the neighboring 2k (k[greater-or-equal, slanted]1) bins, which further reduces the asymptotic mean integrated squared error.
