Statistcs of landslide sizes

The folder contains tools for the statistical analysis of landslide sizes (e.g., area and volume).
Estimation of probability of landslide area
The folder contains the pdf of a poster describing a script for the R free software environment for statistical computing (http://www.r-project.org/) to estimate the probability density of landslide area data, using three method: histogram estimation (HDE), kernel density estimation (KDE), and maximum likelihood estimation (MLE). The script estimates the parameter of three type of distribution used in the literature to describe landslide area distribution: Double Pareto, Simplified Double Pareto, Inverse Gamma. The tool is available through the web as WPS (Web Processing Services) using also open source GIS clients (e.g. QuantumGIS with WPS-Client plugin). Please cite: Rossi et al. 2012. A tool for the estimation of the distribution of landslide area in R. Geophysical Research Abstracts, Vol. 14, EGU2012-9438-1, 2012. For help, comments and suggestions, please refer to Mauro.Rossi@irpi.cnr.it.
Estimation of the probability density of landslide volume data
The folder contains a script for the R free software environment for statistical computing (http://www.r-project.org/) to determine the probability density of landslide volume data, using kernel density estimation (KDE). The folder also contains two demonstrative data sets, and a file with illustrative results. The script was prepared by Maria Teresa Brunetti (MariaTeresa.Brunetti@irpi.cnr.it).
