About GTDR project

This page intends to disseminate to ALL a set of scripts written in R that allow to make several calculations of data analysis (visualization, distribution laws, univariate, bivariate and multivariate statistics) and geostatistics (declustering, calculation of experimental variograms and estimation - inverse power distance, and kriging). For now, geostatistics is implemented in 2D.

The main purpose of these routines is teaching and demonstration, and R is indeed a fantastic tool for this purpose. These scripts are updated frequently, so visit us.

The author can not be responsible for any error, misuse or misinterpretation of the results.
