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
