I write stuff on my website, so I can use it for my work. A lot of data programming and analysis are about copying and pasting old syntax and modifying it for a current/immediate purpose.
I wrote www.estat.us more than ten years ago and I still go there to copy what I need for data management and statistical programming. If you have any questions, please email me at k u e k a w a AT GMAIL COM .
p.s., Due to old age and kidney failure, my dog passed away at the age of 13.5 on January 11, 2016. RIP, Archie. You were the greatest dog.
