See the review

Fantastic reference, thanks Nick.

Thanks a lot, Patrick. --- Patrick Toche. On Tue, 15 Jan 2013 21:59:09 +0800, Nick Cox <njcoxstata@gmail.com> wrote:

Many problems in data management center on relating values to values in other observations, either within a dataset as a whole or within groups such as panels. This column reviews some basic Stata techniques helpful for such tasks, including the use of subscripts, summarize, by:, sum(), cond(), and egen. Several techniques exploit the fact that logical expressions yield 1 when true and 0 when false. Dividing by zero to yield missings is revealed as a surprisingly valuable device. http://www.stata-journal.com/article.html?article=dm0055 On Tue, Jan 15, 2013 at 1:52 PM, annoporci <annoporci@gmail.com> wrote:I doubt that you need to loop, but I am completely in the dark over what it is that you want to do. NickI'm generating indices starting at different dates, so I want to use the value of the variable at some date of my choosing (not the firstdate in the dataset!) to generate an index starting at, say, the value1,by dividing all observations by that value. Very simple.
