Question

Find mode of a chi-square variate with 8 degrees of freedom.​

Answer 1

Answer:

We need to find x∗ such that x∗=argmaxx>0f(x). Then x∗ is the mode. Note that argmaxx>0f(x)=argmaxx>0logf(x), so we will find the mode by maximizing the log of the pdf instead of maximizing the pdf (this turns out to be easier).
