How to select the active variables which have significant impact on the event of interest is a very important and meaningful problem in the statistical analysis of ultrahigh-dimensional data. In many ...
Survival of near-critical branching Brownian motion
ival near-critical branching Brownian motion
2010/11/29
Consider a system of particles performing branching Brownian motion with negative
drift μ = √2 − " and killed upon hitting zero. Initially there is one particle at x > 0.
Kesten [12] showed th...
A weighted estimation method for survival function
Kaplan-Meier estimate order statistics efficiency
2010/9/10
This paper studies a weighted empirical survival function (WESF)for estimating the theoretical survival function. A general efficiency function of this WESF estimator relative to the Kaplan-Meier esti...
A Functional Inequality for the Survival Function of the Gamma Distribution
Error function Incomplete gamma function Density function Survival function Complete monotonicity
2008/7/3
In this note we give a completely different proof to a functional inequality established by Ismail and Laforgia for the survival function of the gamma distribution and we show that the inequality in t...
