  Hippocratic randomness is defined in a similar way to Martin-Lof randomness,
however it does not assume computability of the probability and the existence
of universal test is not assured. We introduce the notion of approximation of
probability and show the existence of the universal test (Levin-Schnorr
theorem) for Hippocratic randomness when the logarithm of the probability is
approximated within additive constant.
