effCont_bks: Continuous Effectiveness as Beta Kernel-smoothed...

In simIReff: Stochastic Simulation for Information Retrieval Evaluation: Effectiveness Scores

Description

Fits a bounded kernel-smoothed distribution to the given sample of scores. In particular, the beta kernel by Chen (1999) is used, as in Chen99Kernel.

Usage

effCont_bks(x)

Arguments

x	a sample of effectiveness scores between 0 and 1.

Value

an object of class eff.cont.bks, which inherits from eff.cont.
