2012/9/17
Freedman [Adv. in Appl. Math.40(2008) 180–193; Ann. Appl.Stat.2(2008) 176–196] critiqued ordinary least squares regression ad-justment of estimated treatment effects in randomized experiments,using Ne...
Some notes on biasedness and unbiasedness of two-sample Kolmogorov-Smirnov test
notes biasedness unbiasedness two-sample Kolmogorov-Smirnov test
2011/7/6
This paper deals with two-sample Kolmogorov-Smirnov test and its biasedness. This test is not unbiased in general in case of different sample sizes.
This set of lecture notes is a much expanded version of lecture notes developed and used by
the first author in courses at Stanford University from 1981 to 1984 and more recently beginning in 2002. T...
Notes on the occupancy problem with infinitely many boxes: General asymptotics and power laws
occupancy problem regular variation asymptotics poissonization species sampling
2009/5/18
This paper collects facts about the number of occupied boxes in the classical balls-in-boxes occupancy scheme with infinitely many positive frequencies: equivalently, about the number of species repre...
Some Notes on Topological Recurrence
Topological recurrence invariant measures iterated function systems laws of pure types
2009/4/24
We review the concept of topological recurrence for weak Feller Markov chains on compact state spaces and explore the implications of this concept for the ergodicity of the processes. We also prove so...

Some notes on improving upon the James-Stein estimator
The James-Stein estimator quasi-admissibility
2010/4/26
We consider estimation of a multivariate normal mean vector under
sum of squared error loss. We propose a new class of smooth
estimators parameterized by dominating the James-Stein estimator.
