fRatioStat    
                        F-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.
