A new class of distributions is defined, called the Mean Exponential Family (MEF). An asymptotic test statistic is derived to examine the homogeneity of a sample from the MEF, and then, expressions are obtained for binomial, Poisson, negative biomial, beta, gamma, normal, Pareto, Laplace, and Raleigh distributions as special cases. As the results confirm a known underlying distribution for many
