Perhaps you should try some spelling variations:
probability ranking » probabilistic ranking, probability sampling, probability learning
statistical effect » statistical effects, statistical expert, statistical aspect
effect probability » effective probability, defects probability, direct probability
fuller c » fuller m, fuller a, fuller 5

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((fuller c) OR (fuller _)) statistical effect probability ranking*".
