请看看 https://sites.google.com/site/rdpackages/,世界最完整之 RDD 资料在此。
黄老师,我刚看了 在安装这些包时 stata提示我如下:
. net install rdmulti, from(
https://sites.google.com/site/rdpackages/rdmulti/stata) replace
remote connection failed -- see help r(677) for troubleshooting
https://sites.google.com/site/rdpackages/rdmulti/stata/ either
1) is not a valid URL, or
2) could not be contacted, or
3) is not a Stata download site (has no stata.toc file).
current site is still
http://www.stata.com/
r(677);
请问有什么办法可以解决吗?谢谢老师
