Logics in mathematics and in daily life: a statistical programming example

implication: if P then Q (P—>Q)
inverse: if not P then not Q (-P—>-Q)
converse: if Q then P (Q—>P)
contrapositive: if not Q then not P (-Q—>-P)
contradition: if P then not Q (P—>-Q)
Mathematically or logically speaking, if the implication statement holds, then the contrapositive holds, but the inverse does not hold, […]

PUTLOG statement
The PUTLOG statement writes a message that you specify to the SAS log.

The PUTLOG statemen…
