effFit: Fit Effectiveness Distributions

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

Description

Attempts to fit the distribution families listed in effCont or effDisc. In the discrete case, the dks distribution is fitted with multipliers 1, 2, 5 and 10. Failure to fit any distribution family results in an error.

Usage

effContFit(x, silent = TRUE)

effDiscFit(x, support, silent = TRUE)

Arguments

x	a sample of effectiveness scores between 0 and 1.
silent	logical: should the report of error messages be suppressed?
support	the support of the distribution (see support).

Value

a list of eff.cont objects fitted to the given data.

See Also

effCont and effDisc for the available distribution families.

See effSelect for model selection, and effFitAndSelect to fit and select automatically.

Examples

e <- effContFit(web2010ap[,1])
str(e, 1)
sapply(e, plot, plot.data = TRUE)

e <- effDiscFit(web2010p20[,1], seq(0,1,.05))
str(e, 1)
sapply(e, plot, plot.data = TRUE)
