Monte Carlo Exact Methods Used for Analysing Interethnic Unions in Great Britain
本文开发了马尔可夫链蒙特卡洛方法，用于估计跨族裔婚姻表的精确条件p值和残差分布，发现除巴基斯坦/白人和其他亚洲/白人组合外，族裔间联姻无性别差异。
The value of using exact rather than asymptotic tests to measure intermarriage in the United Kingdom is examined. "We develop Markov chain Monte Carlo methods for estimating the exact conditional p-value and the exact distribution of the residuals, for quasi-independence and quasi-symmetry. These methods are used to analyse a sparse 10 x 10 symmetric table of interethnic unions, extracted from the 1% household sample of anonymized records from the 1991 U.K. census. With the exception of Pakistani/White and Other Asian/White unions, there is no evidence against quasi-symmetry. We conclude that, with these exceptions, there are no gender differences in the affinities between ethnic groups."
