Inferences

An “inference” is an extrapolation from a state in one state-space to a state in another state-space, where both state-spaces describe the same set of real objects. The state-space from which an extrapolation is made is called the “observed” state-space. The state-space to which an extrapolation is made is called the “unobserved” state-space. With reference to an inference from a state in the state-space {cloudy, not cloudy} to a state in the state-space {rain in the next 24 hours, no rain in the next 24 hours}, {cloudy, not cloudy} is the observed state-space while {rain in the next 24 hours, no rain in the next 24 hours} is the unobserved state-space.
