The program SIREN (SensItivity extended REjectioN program) has been developed at C-JRC-IE by the Probabilistic Risk & Availability Assessment of Energy Systems sector within the Nuclear Safety Unit.

The program SIREN is a tool designed to perform distribution sensitivity analysis on the results of a computer code. The program uses the Extended Rejection Method to perform this kind of analysis [3]. This method, which was developed at the Nuclear Safety Unit, provides a mean to estimate the empiric cumulative distribution function (CDF) of the output when chosen a hypothetic alternative input distribution function (see point 2 for details).

In addition to that main task, SIREN is also able to perform two other tasks. The first one is to check the quality of the sample used to perform the sensitivity analysis. The second one is to perform regression analysis of the output variable (we assume that there is only one output variable under study) versus the input parameters.
