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