Abstract

An understanding of estimable functions is essential when using an overparameterized linear model. The most attractive features of these functions are their invariance property to the solution vector and their wide range of practical applications in agricultural research. This study reviews some of the ways that estimable functions can be used by the agricultural scientist.

Keywords

APPLICATIONS OF ESTIMABLE FUNCTIONS IN AGRICULTURAL RESEARCH WITH SPECIAL EMPHASIS ON THE GLM PROCEDURE OF SAS.

An understanding of estimable functions is essential when using an overparameterized linear model. The most attractive features of these functions are their invariance property to the solution vector and their wide range of practical applications in agricultural research. This study reviews some of the ways that estimable functions can be used by the agricultural scientist.
