DGSA

This package implements distance based generalized sensitivity analysis method (DGSA). For more information about the method please read:

Fenwick, Darryl, Céline Scheidt, and Jef Caers. "Quantifying asymmetric parameter interactions in sensitivity analysis: Application to reservoir modeling." Mathematical Geosciences 46.4 (2014): 493-511.

You can install the package manually or from GitHub:

Manual installation

Clone to your own computer, open Rstudio or R and type:

install.packages("package_Location", repos = NULL, type=source)

You also have an option to load your clone as a project in Rstudio and then proceed with project build Ctrl+Shift+B. This is particularly useful if you plan on adding/modifying features.

Installing from GitHub

First you will need to make sure that you have devtools installed, then you can install with the following command:

devtools::install_github("ogru/DGSA")

After that you can proceed to load the routines in the usual way with library(DGSA).

Examples of usage

To view some of the package capabilities go to the following link:
