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

Refresh some basic logical propositions (or statements):
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, […]
