Exact Sample Size Methods for Estimating Parameters of Discrete Distributions
Xinjia Chen, Zhengjia Chen
In this paper, we develop an approach for the exact determination of the minimum sample size for estimating the parameter of an integer-valued random variable, which is parameteriz…
Sequential Estimation Methods from Inclusion Principle
Xinjia Chen
In this paper, we propose new sequential estimation methods based on inclusion principle. The main idea is to reformulate the estimation problems as constructing sequential random…
New Optional Stopping Theorems and Maximal Inequalities on Stochastic Processes
Xinjia Chen
In this paper, we develop new optional stopping theorems for scenarios where the stopping rules are defined by bounded continuity regions. Moreover, we establish a wide variety of…
Consecutive Sequential Probability Ratio Tests of Multiple Statistical Hypotheses
Xinjia Chen
In this paper, we develop a simple approach for testing multiple statistical hypotheses based on the observations of a number of probability ratios enumerated consecutively with re…
New Sequential Methods for Detecting Portscanners
Xinjia Chen
In this paper, we propose new sequential methods for detecting port-scan attackers which routinely perform random "portscans" of IP addresses to find vulnerable servers to compromi…
