Se propone un indicador que facilita la estimación del modelo lineal de corregionalización (MLC), necesario para la aplicación de la técnica cokriging. A través de un estudio de caso se comparan varianzas de predicción obtenidas con las técnicas kriging y cokriging empleando como variable auxiliar el indicador propuesto. Se muestra, para la información considerada, que el método cokriging resulta preferible en términos de costos y de precisión de las predicciones.
It is proposed an indicator that facilitates the estimation of the linear model of coregionalization necessary for the application of the cokriging method. Through a case study, the prediction variances, obtained by kriging and cokriging methods with the proposed indicator as auxiliary variable, are compared. It is shown, with the considered information, that the cokriging method is preferable in terms of costs and precision of the predictions.
