See http://www.stata.com/statalist/archive/2013-04/msg00301.html for a
comment on expressions like "a data".
The easiest way I know is to -reshape- before and after. Note that
-egen, mode()- won't play with your 4th example, where 3 and 4 tie for
mode, so you need a rule such as -minmode-.
. l
+---------------------------+
| row1 row2 row3 row4 |
|---------------------------|
1. | 1 3 1 4 |
2. | 3 3 4 1 |
3. | 1 4 2 2 |
4. | 4 4 3 3 |
+---------------------------+
. gen id = _n
. reshape long row, i(id)
(note: j = 1 2 3 4)
Data wide -> long
-----------------------------------------------------------------------------
Number of obs. 4 -> 16
Number of variables 5 -> 3
j variable (4 values) -> _j
xij variables:
row1 row2 ... row4 -> row
-----------------------------------------------------------------------------
. egen mode = mode(row), by(id) minmode
. reshape wide
(note: j = 1 2 3 4)
Data long -> wide
-----------------------------------------------------------------------------
Number of obs. 16 -> 4
Number of variables 4 -> 6
j variable (4 values) _j -> (dropped)
xij variables:
row -> row1 row2 ... row4
----------------------------------------------------------------------
