Beyond Linearity And Independence, J. Stuart Hunter

Conference on Applied Statistics in Agriculture

This brief lecture discusses statistical problems associated with postulating and fitting models in engineering and the sciences. Particular emphasis is placed on the two-model problem: the employment of both deterministic and stochastic components within a model. Further, the use of empirical versus theoretical models on the part of both statisticians and experimenters is examined.

Multi-Product Dry Milling Yields Prediction When Products Are Not Independent, Aziz Bouzaher, Alicia L. Carriquiry

Conference on Applied Statistics in Agriculture

The yield of products in the dry milling industry is largely determined by the physical properties of the corn kernel. The main objective of this paper is to investigate several statistical models of dry milling yield prediction based on physical characteristics of corn. Data consisting of one hundred corn samples representing a range of genetic traits and quality differences are used. For each corn sample, sixteen physical and chemical properties together with six dry milling product yields were measured, in a controlled laboratory environment .

For each corn sample, we consider a vector of dry milling product yields, and a …
