HW4 2.2 Question

[Yitong Zhou]

Is there any standard way to get the \theta and \Phi(x), g(\theta) function? Since in this question, we do not know what is \theta beforehand.

Thanks,

Yitong Zhou

Hi!

If i'm not mistaken, for multinomial Normal distributions, \theta is a set of parameters that includes the mean and the covariance matrix, aka \theta = {\mu,\Sigma}

Cheers,

Vagelis

Hi Yitong,

There is a standard way on how to model the normal distribution into exponential family. You can get it by a quick search.

Thanks,

Mu
