setDCF: This function allows to specify the Decision Cost Function

In davidavdav/sretools.R: Compute error metrics and make DET plots for NIST-like Speaker Recognition Evaluations

Description

The decision cost function is typically specified for a particular evaluation, and does not change all the time. Hence we keep the parameters as globals in an environment .sretoolsEnv. This function allows to change the parameters.

Usage

setDCF(evaluation, prior=0.5, cfa=1, cmiss=1)

Arguments

evaluation	A stirng indicating the evaluation, “nist” or “evalita”
prior	the target prior
cfa	the cost of a false alarm
cmiss	the cost of a miss

Details

By specifiying evaluation the whole cost function can be set immediately.

Alternatively one or more parameters prior, cfa or cmiss can be specified.
