# Talk:Moment closure

You're right. "The estimates for the mean and variance were obtained by setting ${\displaystyle \mu _{3}(t)=3\mu _{2}(t)\mu _{1}(t)-2\mu _{1}(t)^{3}}$ that is, the normal approximation that corresponds to setting cumulants of order 3 and above to be 0."ref I'll try to clarify this in the article.
