A reverse martingale property that characterizes the natural exponential family with quadratic variance function

Statistics & Probability Letters, 2000
We give a characterization of the natural exponential family with quadratic variance function in terms of a discrete-time reverse martingale-like property. The proof of this result is based on the properties of the set of UMVU estimable functions.

Using the quadratic Box-Cox for flexible functional form selection and unconditional variance computation

Empirical Economics, 1994
A quadratic Box-Cox methodology is presented for choice of flexible functional form that includes consistent computation of variance estimates. Empirical viability of the procedure is investigated by specifying a dual profit function using highly aggregated U.S. agricultural data.

A property of natural exponential families in n with simple quadratic variance functions

Journal of Statistical Planning and Inference, 1997
Suppose that \(F\) is a natural exponential family \(\{a(\theta) \exp (\theta x)f(x) dx\); \(\theta\in\Theta\}\) on \(\mathbb{R}\), which is absolutely continuous with quadratic variance \(V_F (m)\) defined on the mean domain \(M_F\). \textit{B. Jørgensen} et al. [Can. J. Stat. 17, No.

Empirical Bayes Confidence Intervals for Means of Natural Exponential Family‐Quadratic Variance Function Distributions with Application to Small Area Estimation

Scandinavian Journal of Statistics, 2008
Abstract. The paper develops empirical Bayes (EB) confidence intervals for population means with distributions belonging to the natural exponential family‐quadratic variance function (NEF‐QVF) family when the sample size for a particular population is moderate or large.

Introduction to Morris (1982) Natural Exponential Families with Quadratic Variance Functions

1997
Morris’ paper has distinctly two parts: the first one sets the stage for natural exponential families, or NEF (Sections 1, 2, 7, 9, and 10); the other one concentrates on NEF with quadratic variance functions, called QVF by Morris. Let us call their set “Morris class,” he deserves it.
