9.2 최대가능도 추정법 — 데이터 사이언스 스쿨

https://datascienceschool.net/02%20mathematics/09.02%20%EC%B5%9C%EB%8C%80%EA%B0%80%EB%8A%A5%EB%8F%84%20%EC%B6%94%EC%A0%95%EB%B2%95.html

복수의 표본 데이터가 있는 경우의 가능도함수에서

def likelihood(mu):
return (2 * np.pi * sigma2) ** (3 / 2) * np.exp(-(3 * mu ** 2 + 4 * mu + 10) / (2 * sigma2))
여기서
return (2 * np.pi * sigma2) ** (-3/2) * np.exp(-(3* mu ** 2 + 4 * mu + 10) / ( 2 * sigma2))
이거 아닌가요? 지금 보면, -3/2 였던 게 3/2 로 잘못표기된 것 같습니다.
