Density and Hazard Rate Estimation for Right-Censored Data by Using Wavelet Methods
利用小波方法估计右删失数据的密度与风险率
Summary This paper describes a wavelet method for the estimation of density and hazard rate functions from randomly right-censored data. We adopt a nonparametric approach in assuming that the density and hazard rate have no specific parametric form. The method is based on dividing the time axis into a dyadic number of intervals and then counting the number of events within each interval. The number of events and the survival function of the observations are then separately…
