摘要：
Most present research on diagnostic reasoning has dealt with discrete causal relationships. However continuous causal models, particularly regression models, are frequently encountered in many applications, especially in equipment/instrument diagnostic applications. A unified diagnostic reasoning model that deals with both continuous as well as discrete causal relationships is presented. The diagnostic model significantly extends the formal probabilistic diagnostic reasoning model of Peng and Reggia and other works. Statistical theories are used to formally derive conditional causation probabilities based on continuous system models. The derived conditional causation probabilities can be used along with discrete causal relationships provided by experts to find the most probable diagnostic hypothesis for a given set of observations.
