本人采用PSM进行逐年匹配,其它年份均运行正常,独有此2009年遇到困难。匹配变量为tfp、lnage、lnsize、lnkl、des_ex、a_l,du为处理变量,在使用PSM进行匹配时stata处于一直运行中,出来不了结果。采用的是最近邻匹配,程序为:psmatch2 du tfp lnage lnsize lnkl des_ex a_l,logit neighbor(2) common caliper(0.05)
现用dataex截取200个数据样本如下,恳请大神指点!不胜感激~~
input float(du tfp) double(lnage lnsize lnkl des_ex a_l)
