The ratio of the hit rates for <i>ANSWER</i> and <i>ANSWERS</i> (in columns) against those of linear regression of mean deviation (<i>MD</i>), point-wise linear regression (<i>PLR</i>) of differential light sensitivity and <i>ANSWER</i> (in rows).

The false positive rate (FP) at which the ratio was estimated is also given. The ratio is calculated for criteria giving 5% false positive rates, or at a false positive rate closest to 5% for point-wise linear regression where the false positive rate cannot be continuously estimated. The comparison was carried out with series lengths of 5, 7, 9 and 11.
