Dear Stata users,

Most of the time, we use -tabstat- to displays summary statistics for variables that is calculated (conditioned on) another variable. Now if I want to display variable's mean (or any statistics else) that is calculated separately other variables (suppose those variables all have same number of categeries, for example, group variables created using different methods), how can I achieve it?

Code:

groups    |        1st         2nd          3rd           4th          5th
----------+----------------------------------------------------------------
        1 |       4.026       4.126         4.726        4.326        4.026
        2 |       5.435       5.335         5.335        5.735        5.035
        3 |       7.311       7.301         7.331        7.321        7.311
        4 |      10.274      10.374        10.374       10.674       10.174
        5 |      13.346      13.346        13.246       13.346       13.646
