RE: st: RE: Changing -correlate- results
I've tried both the -egen- and -sort, stable- approaches; each gives me
identical results after each execution of the do file. With -egen- the
correlation coefficient is always 0.7498, and with -sort, stable-, the
result is always 0.7608. I suppose the difference in the two results lies in
how tied ranks are treated. Thank you all very much.
From: "Scott Merryman" <email@example.com>
Tied values are randomized. From the helpfile:
"Note: ties in the sort index (i.e., identical sorting values) are broken
an arbitrary (i.e., random) order, unless the stable option is specified."
You might try:
sort f1, stable
sort f2, stable
Hope this helps,
