Abstract
In many practical applications, the research object can only produce two results, and their distribution follows binomial distribution. In the age of big data, the scale of data streams available for monitoring will continue to grow, and there is an unprecedented demand for an efficient monitoring scheme for high-dimensional binomial data streams . However, the existing monitoring scheme is to directly apply the error detection rate (FDR) control program to the data at each time point. The generated process will not control the global FDR, and users will not be able to obtain the desired controlled average running length(IC ARL). In order to solve these problems, this paper adopts a two-phase monitoring scheme motivated by Li(2018) that constructed the two-phase control chart for normal distribution concerning both global FDR and pointwise FDR. In the first stage, it detects whether there is a data flow that is out of control, and in the second stage, it detects the specific location of the data flow that is out of control. Numerical simulation show that the proposed two-phase monitoring scheme based on binomial distribution outperforms the existing methods.
