Efficient estimation of Weber’s W

摘要: Many studies rely on estimation of Weber ratios (W) in order to quantify the acuity an individual’s approximate number system. This paper discusses several problems encountered estimating W using standard methods, most notably low power and inefficiency. Through simulation, this work shows that can best be estimated a Bayesian framework uses inverse (1/W) prior. beneficially balances bias/variance trade-off and, when used with MAP is extremely simple implement. Use scheme substantially improves statistical examining correlates W.
