Inheritance Formula

Inputs: subset.mean and inh.mean

Outputs: mean = (subset.mean + inh.mean)/2

Consistency conditions: none

Comment: This formula caused some confusion. In PLN we distinguish two types of inheritance, intensional and extensional. Subset is another name for extensional inheritance. This formula gives the mean of the intensional and extensional inheritance and is sometimes referred to as mixed inheritance.
