Tutorial on STATA

Welcome everyone in my tutorial on STATA.

(This is to inform you that, I intend to update this page as my knowledge updates. And this is prepared from different web resources that are acknowledged and figured at Reference. However, any errors are my sole responsibility)

This page will allow the STATA learners to learn the tips and tricks for data management for statistical and econometric analysis.

STATA,Data Analysis and Statistical Software, is now widely used by the researcher in several fields (specially by economist). The recent versions of STATA enables both command based and menu based option for operation. However, its recommended by most STATA users to use command based options. The probable reason might be that the command line usage has the invaluable advantage that all steps of the analysis,and thus all results, are easily replicable (Pfaff, 2009).

However, Welcome again  in the journey with STATA!

STATA Software: First- one need to have STATA installed. Perhaps you might be aware that there are four different packages available: Stata MP (multi-processor either 2 or 4 processors) which is the most powerful, Stata SE (special edition), Intercooled STATA and Small STATA. The main difference between these versions is the maximum number of variables, regressors and observations that can be handled (Lembcke, 2010).

Running STATA programme one will get four windows:

– window 1: Result window (it displays the results estimated from data set)
– window 2 : Command window (here we have to tell STATA what to do in STATA’s  own language (commands, here))
– window 3 : Command review (one can look at the previous commands)
– window 4 : Variable review (variable used in memory/ the variables of the data set you are using)

Four windows of STATA

One  can enter commands in either of three ways:
– Interactively: you click through the menu on top of the screen
– Manually: you type the first command in the command window and execute it, then the next, and so on.
– Do-file: type up a list of commands in a “do-file”, essentially a computer programme, and execute the do-file.
