This application allows the user to generate networks for crime linkage situations with two offenders according to the method introduced in [de Zoete, 2015]

In the Set parameters tab, the user can specify

* The number of crimes.

* The number of different types of evidence.

* The number of people in the potential offender population, the prior distribution of the offender configuration node is based on this number.

* The random match probabilitites belonging to the different types of evidence.

* For each case, which of the different types of evidence was observed in this case.

In the Set probabilities and plot network tab, the user can specify the random match probabilities associated with the different types of evidence. Together with setting the number of people in the potential offender population this sets all the necessary (conditional) probabilities.

The application generates the network associated with these settings in real time. A graphical representation of this network is plotted. The network can be downloaded (using the ) download network text/button as .net file. Software packages like AgenaRisk, Genie and Hugin can be used to examine the network, add extra nodes and make computations.
