这个中国很缺啊

i only studied two books about stata, both introductory: one by STATA, the other by Hamilton.

after that introductory learning period (about two years), I learn about more advanced topics when I need them, by consulting the STATA manuals and stat/econometrics books. remember: practice makes perfect.

my opinion is that you don't need such a book, unless you are a statistics or econometrics student.

thank u for ur valuable advice  
what if i am a western economics graduate student
do i  need to learn more  ?
i need some infomations about  how to  find the best regress
recently i regress something but don't know   . i need to learn more detail stuff  about regress
what should i do
