Mixtures of equispaced normal distributions and their use for testing symmetry with univariate data
收藏 引用
COMPUTATIONAL STATISTICS & DATA ANALYSIS 2014年 71卷 262-272页
作者: Bacci, Silvia Bartolucci, Francesco Univ Perugia IT Dept Econ Finance & Stat Perugia Italy
Given a random sample of observations, mixtures of normal densities are often used to estimate the unknown continuous distribution from which the data come. The use of this semi-parametric framework is proposed for te... 详细信息
