Re: st: identifying strings that differ on one or two letters

[Dalhia <ggs_da@yahoo.com>]

Hi,
I tried both techniques suggested by the list (thank you Dmitry and Scott). But neither seem to work, and I am hoping you can tell me what is wrong. 

I can't seem to load "strgroup." When I try to install it on stata 11, it gives me the following message:

"package does not contain strgroup.plugin for WIN64A platform could not load strgroup.pkg from http://fmwww.bc.edu/RePEc/bocode/s/";

I'm sure there is a simple fix, but my stata code knowledge is very basic, and I'm not sure how to fix this problem. 

I also tried Soundex, but it identifies completely different companies as the same. For example, suniti commercials ltd, sunnytex investments pvt ltd, sunteck realty & infrastructure ltd, syndicate bank, all get the same soundex code S532. And soundex does not seem to allow any options that might limit matches to names that are very similar. 

Any suggestions? 

Thanks. I appreciate your help.
