Estimates of Percentile Regression Lines Using Salary Data
利用薪资数据估计百分位回归线

In addition, investigators are often more interested in estimates of percentile lines than in the mean regression line. Thus, a modification of Brown-Mood regression is proposed to estimate the (100p) th percentile line α + βx of a random variable.
