Abstract: The current research studies in medical sciences involve data that are randomly collected during the time over specified locations. We use geostatistical techniques such as the variogram and kriging approaches to uncover the spatial correlation in structural magnetic resonance imaging (sMRI) data and to predict the effect of a brain tumor on brain regions. We propose various variogram model approaches for some brain slices containing a brain tumor and the best model is selected by using the cross-validation method in kriging. A bootstrap resampling method is used to estimate the parameters of the selected models.
