This repository contains the code for a plugin for [QGIS](https://www.qgis.org), called "Susceptibility Zoning plugin" (SZ-plugin), aiming at creating maps of susceptibility to various natural forcing elements.

The plugin has been developed with a main focus and application towards landslides susceptibility, but it can be applied to different types of natural events or inter-disciplinary applications.

_Data preparation_ functions can be used for data pre-processing
_SI_ functions run the statistic models for susceptibility, cross-validate by a simple random selection of train/test samples and evaluate the prediction capacity by ROC curves
_SI k-fold_ functions run the statistic models for susceptibility, cross-validate by k-fold method and evaluate the prediction capacity by ROC curves
_Classify SI_ functions allows to cathegorize the susceptibility index into _n_ classes on the base of AUC maximization.
