SCORE TEST PARA EL EFECTO DEL COEFICIENTE DE SOLAPAMIENTO EN MODELOS DE SUPERFICIES DE RESPUESTA DE PRIMER Y SEGUNDO ORDENSCORE TEST FOR THE OVERLAP COEFFICIENTE EFFECT ON FIRST AND SECOND ORDER RESPONSE SURFACES MODELS. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.165, pp.234-245. ISSN 0012-7353.

In this article, a test has been proposed for the overlap coefficient for Draper and Guttman´s model using response surface models of first and second order. The test is based on the Score test of Rao and makes use of the theory of perpendicular projection operators. The test may be used in different neighborhood patterns whenever the closest neighbor can be considered as the experimental unit directly affected by the treatments and the response surface models be of first and second order. The method is simple to adopt and can be implemented in the field of Agronomy or marketing research since it’s asymptotic nature is in agreement with the large number of experimental units generally present in this type of researches.
