This last brought forth a good chuckle. Perhaps combine them into a single entry?
On a serious note, to have someone of significant experience say that they hadn't heard of
SAS's method for doing "x", for nearly any x, marks a welcome climate change. (And took
nearly that long.)
The phreg procedure also added a "Scheffe test" of the overall hypothesis, by the way,
which no one here has yet back-engineered to figure out what they are doing. An F-test?
