 Autoria: VIEIRA, S. R.; CARVALHO, J. R. P. de; PAZ GONZÁLEZ, A. The semivariogram function fitting is the most important aspect of geostatistics and because of this the model chosen must be validated. Jack knifing may be one the most efficient ways for this valida... ... |
 Autoria: VIEIRA, S. R.; CARVALHO, J. R. P. de; CEDDIA, M. C.; PAZ GONZÁLEZ The use of geostatistics requires at least that the intrinsic hypothesis be satisfied. The presence of a trend in the data invalidates this hypothesis. One of the ways of solving this problem is by su... ... |
