I was encouraged by these findings, and considered that the first alteration for Lertap would involve getting it to compute the H-H index. In July 2005 a new version of Lertap, “5.5”, was released, one which featured the computation of the H-H index. This version was also capable of producing a data file formatted for direct input to Wesolowsky’s “SCheck” program – this was done so that Lertap users would have recourse to a rigorous statistical procedure for testing the null hypothesis of response independence, in a manner analogous but not identical to that used by Harpp and Hogan (1993).
