  abstract     = {This note will give a brief derivation of Stirling's approximation. This bound is often useful for factorials. x ! ≈ x x e − x 2 π x ​ ⟺ ln x ! ≈ x ln x − x + 2 1 ​ ln ( 2 π x ) This proof (more like an interesting justification). is taken from page 2 of (MacKay 2003) . Let's sta}
