  • CONDITIONAL SIMULATION OF RANDOM FIELDS BY SUCCESSIVE RESIDUALS 
    Vargas-Guzman J.A.; Dimitrakopoulos R. (2002)
    This paper presents a new approach to the LU decomposition method for the simulation of stationary and ergodic random fields. The approach overcomes the size limitations of LU and is suitable for any size simulation. The ...
  • COREGIONALIZATION BY LINEAR COMBINATION OF NONORTHOGONAL COMPONENTS 
    Vargas-Guzman J.A.; Warrick A.W.; Myers D.E. (2002)
    This paper applies the relationship between the matrix multivariate covariance and the covariance of a linear combination of a single attribute to analyze modeling with nested structures. This analysis for modeling of ...
  • GEOSTATISTICS FOR POWER MODELS OF GAUSSIAN FIELDS 
    Vargas-Guzman J.A. (2004)
    This paper introduces geostatistical approaches (i.e., kriging estimation and simulation) for a group of non-Gaussian random fields that are power algebraic transformations of Gaussian and lognormal random fields. These ...
  • SUCCESSIVE NONPARAMETRIC ESTIMATION OF CONDITIONAL DISTRIBUTIONS 
    Vargas-Guzman J.A.; Dimitrakopoulos R. (2003)
    Spatial characterization of non-Gaussian attributes in earth sciences and engineering commonly requires the estimation of their conditional distribution. The indicator and probability kriging approaches of current nonparametric ...
