Using Latent Variables in Model Based Clustering: An E-Government Applicationd in order to evaluate the quality of a public company and to define the policy priorities. In this chapter, we confront the problem of clustering public organizations with model-based clustering, and we assume each observed binary indicator to be generated from a latent continuous variable.

Simulations are carried out to illustrate the improvement achieved in terms of bias and mean square error. The proposed estimator is applied on a financial dataset dealing with durations between violations in a quantitative risk management environment.
