Statistical Problems of Joint Research

Abstract

inference. Hence, a discussion under the subject of statistical problems of joint research, as cast under the general topic of Economic Implications of Agricultural Experiments must deal basically with the problem of making inferences-specifically inferences dealing with economic decisions, in which experimental data are involved. A basic assumption is that these inferences are in the form of optimal decisions, or leading to optimal decisions. The nature and quality of such inferences depend, first of all, upon the thinking behind the planning of experiments, as well as on their proper execution and basic interpretation. When these experiments are part of a joint research project, statistical problems likely will be compounded, for regardless of the singleness of the prime objective, specific secondary objectives related to the individual components of the joint effort are almost certain to be included. The purpose of this discussion is to examine the basis for what might be termed problem areas in the joint research effort between economists and agronomists, soil scientists, animal scientists, and other related areas, and to suggest a few general approaches to some of these problems to make them more tractable. Some of the broader and more general problems will be discussed, since these must be well understood before useful solutions of more specific problems can be made. This discussion is much in the nature of a review, since most of the specific statistical problems have been treated in detail by writers who will be referred to in the appropriate sections.
