UNA ALTERNATIVA PARA DETECTAR OBSERVACIONES INFLUYENTES EN FUNCIONES DE PRODUCCIÓN UNIVARIADAS

L.F. RINCÓN L.A. LÓPEZ A.F. IEMMA About the authors

Models of production functions Yi = (Xi , <FONT FACE="Symbol">q</font>) + e, with explanatory variables xj , j=1,..., k and a parameter vector <FONT FACE="Symbol">q</font> are used in agricultural and biological areas. In the present work we present an alternative to detect influent observations, when the production function is univariate and the Gauss-Newton method is used to estimate the parameters.
