The Influence of Prince on Sleeping Time: An Empirical Study Based on Propensity Score Matching

Abstract

With the rapid development of science and technology, it is of great significance to study the influence of prince on sleeping time to explore the knowledge value of sleeping beauty. In this work, we use the data of American Physical Society to identify sleeping beauties according to B-index, and use logistic model and propensity score matching model to analyze the data. Then, we explore the impact of prince on the sleeping time of sleeping beauty. The results show that the prince has a significant inhibitory effect on the sleeping time of sleeping beauty, and the sleeping time of sleeping beauty cited by prince is shorter. The citation behavior of prince has the feature of self-selection. Using propensity score matching method can effectively overcome the problem of sample selection bias and obtain more reliable estimation results.
