```Dear Ashim,

you may want to do one or another, and with some experience you will
feel what is right. Most or all of your questions are answered in
pretty much any Stata introduction guide. There is plenty of them in
the internet, e.g.
http://www.nyu.edu/its/statistics/Docs/Intro_stata5.pdf by Robert A.
Yaffee
or
http://www.folkesundhed.au.dk/uddannelse/software/besked.pdf by Svend Juul,
and many others written specifically for beginners.

The link to the UCLA website for Stata is attached to every message
sent to Statalist.

If you want something more interactive, you may benefit from the Net
Courses conducted by Stata, Corp. The schedule and details are
available on their website:
