Inputting ASCII files using infile, insheet or infix i. For example, Smultron is an open-source software that works well with Stata. dta to open it, or you can do something fancier to achieve the same goal – like write some codes.

As a prefix: Josef Brüderl, Useful Stata Commands, SS 2012 Folie 13 The basic idea – This does the computations separately for each panel: sort id by id: command-bysort id:is a shortcut – If the time ordering within the panels is important for the computations then use sort id year by id: command-bysort id (year): is a shortcut The prefix “ bysort ” is a combination of “by” and “sort” you could equivalently break it into two commands, but it is generally simpler to use "bysort" Stata will first sort the data, then return the information by category. Suppose we wanted to calculate the minimum value of age for each marital status.
