2 CHAPTER 8. THE EXPONENTIAL FAMILY: BASICS where we see that the cumulant function can be viewed as the logarithm of a normalization factor.1 This shows that A(η) is not a degree of freedom in the speciﬁcation of an exponential family density; it is determined once ν, T(x) and h(x) are determined.2 The set of parameters ηfor which the integral in Eq.

### Chapter 9 The exponential family: Conjugate priors

people.eecs.berkeley.edu

For exponential families the likelihood is a simple standarized function of the parameter and we can deﬁne conjugate priors by mimicking the form of the likelihood. Multiplication of a likelihood and a prior that have the same exponential form yields a posterior that retains that form.

Two other ways to motivate an extension of the exponential function to complex numbers, and to show that Euler’s formula will be satis ed for such an extension are given in the next two sections. 3.1 ei as a solution of a di erential equation The exponential functions f(x) = exp(cx) for ca real number has the property d dx f= cf

The Exponential Form of a Complex Number 10.3 Introduction In this Section we introduce a third way of expressing a complex number: the exponential form. We shall discover, through the use of the complex number notation, the intimate connection between the exponential function and the trigonometric functions. We shall also see, using the ...
