Dear Stata Users,
 
I have another data management question and I hope on the same helpful
and great reply than the last time (thanks again to Carole and Nick).
 
 
I have a dataset with the following structure:
 
ID                    TimeA
1                      10
1                      10        
1                      12
2                      8
2                      8
3                      19
3                      21
3                      86
3                      7
4                      10
5                      18
6                      56        
6                      56
...
 
 
And I would like to format the dataset into the following structure:
 
ID                    Time1             Time2              Time3
Time4
1                      10                10                 12
2                      8                  8
3                      19                21                 86
7
4                      10
5                      18
6                      56                56
...
 
 
In words, the values witch are summarized under the label TimeA should
be summarized within a row in the new data structure as long as they
have the same ID. Further each ID-time should get its own column. 
 
I hope you might be able to help me. I really appreciate for any
suggestions.
 
Simon
