It is well known that the quality of plastic electronics, printed circuit boards (PCB), and Organic Light Emitting Diode (OLED) displays can be variable in production. This in turn may lead to an increasing number of faulty batches. Digital radiography and pattern recognition allow inspection of the products non-destructively in real time to increa...

There is growing interest in Statistical Software Testing (SST) as a software assurance technique. While the approach has major attractions, there is a need for new statistical models to infer failure probabilities from SST. The paper constructs a simple but realistic case in which the traditional Binomial model does not work. The paper shows that...
