The Interpretation of Forensic Evidence Using a Likelihood Ratio
研究了如何用似然比解释窗玻璃碎片的折射率测量值，以判断碎片是否来自同一来源，并区分这一判断与嫌疑人是否有罪的问题。
Forensic scientists often have to interpret refractive index measurements made on fragments of window glass, some taken from the scene of a crime and some found on a suspect. Adopting a model used recently by Lindley (1977) and Seheult (1978) this contribution proposes a non-Bayesian solution based on a likelihood ratio. The problem of deciding whether the fragments have come from a common source is distinguished from the problem of deciding the guilt or innocence of the suspect.
