TY - JOUR T1 - On Some Properties and Estimation of a Skew Symmetric Density Function TT - برخی ویژگی‌ها و براورد تابع چگالی چوله JF - srtc-jsri JO - srtc-jsri VL - 5 IS - 2 UR - http://jsri.srtc.ac.ir/article-1-121-en.html Y1 - 2009 SP - 161 EP - 170 KW - Skew-distribution KW - skew-normal KW - skewness KW - kernel estimation N2 - In this paper we consider a general setting of skew-symmetric distribution which was constructed by Azzalini (1985), and its properties are presented. A suitable empirical estimator for a skew-symmetric distribution is proposed. In data analysis, by comparing this empirical model with the estimated skew-normal distribution, we show that the proposed empirical model has a better fit in density estimation, via some simulations.
