 ## What is Spey?
 
 Spey is a plug-in based statistics tool which aims to collect all likelihood prescriptions under one roof. This provides user the workspace to freely combine different statistical models and study them through a single interface. In order to achieve a module that can be used both with statistical model prescriptions which has been proposed in the past and will be used in the future, Spey uses so-called plug-in system where developers can propose their own statistical model prescription and allow spey to use them.
