ef Example data of human single neuron responses to presentation of emotional faces. fRatioStat F-ratio statistic for grouped responses. LL1WayAnova Log-likelihood ratio statistic for grouped responses. relBackgroundLL Log-likelihood ratio of grouped responses being drawn from a background distribution with known mean and variance. sumSqCat Weighted sum of squared deviations test statistic, as used in the changes from background test (CBT).
This package provides functions for testing whether grouped responses have significant deviations from baseline. It allows testing using the non-parametric changes from background test (CBT), which doesn't require multiple testing relative to baseline followed by a second test for an effect of group on the responses. Such double testing can lead to erroneous conclusions, as discussed in Steinmetz & Thorp, 2013.
The primary function is
sumSqCat which computes the appropriate test statistic for use in the CBT. A variety of other test functions are provided which can
be used for comparison of performance.
