我在看分位数回归的时候,看到一篇文章,按照文章作者的指引,找到数据,但是打不开,求助大家!
地址:http://www.econ.uiuc.edu/~roger/research/intro/intro.html
里面数据格式是压缩格式(A gzipped version of the data for the birth weight section of the paper is available in R's compressed save format here, (In R see the documentation for save())> Warning: this data file is 2.3Mb, and 198377 observations on 19 variables.),不知道怎么打开,求助大家,谢谢
