Abstract

This work deals with some aspects of the statistical analysis of complex technological systems. Its aim is the formulation of a final judgement on the expected stochastic behaviour of a given system, when information is mainly of a possibly subjective nature and collected through different channels: elicitation of experts, simulation and experimented data. The model assumed for the system's responses is a regression equation relating the (nx1) vector of observations to a (nxk) non-stochastic design matrix, a (kx1) parameter vector and the (nx1) error vector, assumed to be normally distributed. The problem discussed is how to fit a pooling of information, having different credibility degrees, on a unique interpretation model and how to assess the importance of each variable.
