I have a variable that is right-skewed.  I used the the ladder command
to see suggested transformations. However, no transformations appeared
in the output. I'm guessing that this does not mean the raw form is
better, because there is an option for 'raw' on this list.

Here is the output for the sum, detail command for the variable:



sum disp_2000, detail

      Number displaced 2000 (if data unavailable go up
                           to 2003
