Dear All, I found this question here (https://bbs.pinggu.org/thread-7419648-1-1.html). The data is
Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input str14 address str1 name int test
"A company"  "A" 1
"B company"  "B" 1
"C company"  "C" 1
"D company"  ""  0
"G company"  ""  0
"BD company" ""  1
"E company"  ""  0
"AF company" ""  1
end
Given `address' and `name', I'd like to define a dummy `test' which is equal to 1 if the company name in `address' matches any one of elements of `name', 0 otherwise. Any suggestions are highly appreciated.
