看国外某篇文献时遇到一个疑惑百思不得其解,
原文如下:“Sales Growth(GS) is the change in net sales divided by prior-year net sales. Sales growth GS/10 is the decile of the firm's sales growth in the prior year relative to NYSE firm's decile breakpoints.”
前半句很好理解,是销售增长率的定义,但后半句GS/10的定义我就看不明白了,何为relative to NYSE firm's decile breakpoints?
另外作者在统计性描述里给出的此指标的描述性统计如下:
N Mean SD MIN MAX
GSt-1(Decile) 1,529,508 5.94 3.16 1 10
