如题。想repliacate一遍event study

按照指示在stata中写了一下指令use http://dss.princeton.edu/sampleData/eventdates.dta  /* about 11k */
save H:/thesis/eventdates
use http://dss.princeton.edu/sampleData/stockdata.dta[/url], clear  /* about 90m */
save H:/thesis/stockdata

但是只出现
file http://dss.princeton.edu/sampleData/eventdates.dta not found
server says file permanently redirected to [url]https://dss.princeton.edu/sampledata/eventdates.dta
无法得到数据。求大神分享
