Normal distribution as an exponential family
WebLater, we'll discuss why we require the response to be from the exponential family, but for now, let's just get some practice with this exponential family of distributions. Let's show that if we have a random variable that's binomially distributed with parameters n and p, where n is known and p is potentially unknown, let's show that this is a member of the … Webexponential family". If fq, q 2 is an exponential family, then fx : fq(x) >0g= fx : h(x) >0g which does not depend on q values. This fact can be used to show a family is non …
