Something useful to know about MLEs is that if g is a function, and which function g is does not depend on any parameters being estimated, then the MLE of g ( α) is g ( α ^) where α ^ is ...

Therefore, if the data has a normal distribution, it also has a Mesokurtic distribution. 2) Leptokurtic [high and thin] When the kurtosis > 0, there are high frequencies in only a small part of the curve (i.e, the curve is more peaked)
