Statistics & Probability Letters, 2000, vol. 49, issue 4, 355-363

Abstract: Distributions with normal conditionals have biquadratic regression functions. Consequently, in contrast to classical bivariate normal distributions, their densities can be multimodal. Criteria for determining the number of modes are discussed and illustrations of representative multimodal densities are provided.
