摘要:介绍了分位数回归的概念、拟合优度、置信区间,并将分位数回归方法应用到肺活量的研究中.结果表明,体重在肺活量分布上的变化趋势是递减的,呼吸差在肺活量分布上的变化趋势是递增的,而在肺活量分布的中端,胸围的影响较强.

关键词: 分位数回归, 参数估计, 肺活量

Abstract: The concepts of quantile regression,the goodness of fit,and the confidence interval are introduced.The method of quantile regression is applied to the research on lung capacity.It is concluded that the weight distribution in lung capacity has the tendency to decrease,the breathing difference distribution in lung capacity has tendency to increase,and the chest circumference has strong impact in the middle part of lung capacity distribution.

Key words: quantile regression, parameter estimation, lung capacity
