WebAug 20, 2024 · 5. Log of probability zero is just log of zero as usual, and so indeterminate. That's not fatal to other uses. With entropy we say p log p ≡ 0 whenever p = 0, which can be justified more rigorously. Logarithms can be useful to the extent that probabilities multiply, and for other reasons. The logarithm of a probability density can be useful ...
