매우 가까운 두 수가 x1, x2로 주어져 있을 때
log(x2/x1) = 곧 x1에서 x2로의 변화분(percentage) = (x2-x1) / x1

Why is it that natural log changes are percentage changes? What is about logs that makes this so?
Can somebody explain how the properties of logs make it so you can do log linear regressions where the coefficients are interpreted as percentage changes?
