Does anyone have good references for INTERPRETATION in relation to size of
the spearman correlation coefficient.
For a certain project we had to do many tables of these estimates and I
produced a wrapper for the ci2 (by Poul Seek) and the spearman commands
one can get this output, which is easy to convert to a table in word by
copy and paste, plus select the output as a block and "convert to text".
If you dislike the ";" (e.g. because you are not a word user) the just omit
that part.
The same principle can be suded for any procedure where you want only
estimates (here r(N) etc) and not the remaining texts of that command. The
reason for "version 6" is that ci2 works only in version 6.
