| Abstract: | 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 |
