Abstract

Regression analysis of dummy variables with effect code showed the same results of the analysis of variance table when they applied on three fixed model designs. The designs were: completely randomized, randomized complete blocks and Latin square. This procedure gave an advantage upon the classic one, it yield additional information about the relation between the response and predictors as the regression analysis does, such as: coefficient of determination, identification of the outliers, also tackled the missing observations with out estimated them.
