BAUMGARTNER2014_SIMILARITYESTIMATION
Similarity estimation with listener-specific sensitivity

Usage:

si = baumgartner2014_similarityestimation(sigma)

Input parameters:

sigma

internal distance metrics

Output parameters:

`si`	similarity indices

Description:

baumgartner2014_similarityestimation(...) maps internal distance metrics to similarity indices according to listener-specific sensitivity

baumgartner2014_similarityestimation accepts the following optional parameters:

`'S',S`	Set the listener-specific sensitivity threshold (threshold of the sigmoid link function representing the psychometric link between transformation from the distance metric and similarity index) to S. Default value is 1.
`'gamma',G`	Set the degree of selectivity (slope of the sigmoid link function representing the psychometric link between transformation from the distance metric and similarity index) to G. Default value is 6.
