This method can remodel an estimated distribution and the remodeling method is motivated by the powersbased idea described in Eq. 8 Specifically, given a retrieval model and its estimated document relevance distribution Sq , the remodeling method will raise every probability in Sq to the powers (f (q)) and then normalize the revised probabilities. It can be formulated as: 1 Sq (d) = [Sq (d)] f (q) d ∈D [Sq (d 1 (10) )] f (q) where Sq denotes the remodeled distribution, and the powers f (q)(> 0) is a function for the query q.

Firstly we show how average precision can be inferred from a mixture distribution. Secondly, we conduct an extensive evaluation of several mixture models for a number of metrics (one of which is the task of inferring average precision accurately), and advocate the use of the log-normal model in particular. Interestingly, we show that the best method of estimating parameters for the task of inferring average precision, is the method of moments (MME), rather than maximum likelihood estimates (MLE).
