The partition <math>\pi</math>, in order for it to be defined as a partition of causal relevance, must have these properties:

A partição <math>\pi</math>, para que seja definida como uma partição de relevância causal, deve ter essas propriedades:

#For each subclass <math>C_i</math> the condition must apply <math>rc=P(D \mid C_i)- P(D )\neq 0, </math> ie the probability of finding in the subgroup <math>C_i</math> a person who has the symptoms, clinical signs and elements belonging to the set <math>D=\{\delta_1,\delta_2,...,\delta_n\}</math>. A causally relevant partition of this type is said to be '''homogeneous'''.
