  • Receiver Operating Characteristic (ROC) Curve

Weighted Cohen’s Kappa function – a new function WKAPPA has been added which calculates the weighted version of Cohen’s kappa. The website has also been updated to explain this statistic

New reformatting functions  a number of new supplemental functions have been added which make it easier to format data. These include

QSORTRows: sort rows in a range based on the values of one column in the range.

SortRowsUnique: sort the rows in a data range eliminating any duplicates. There are also the related functions: SortRowsCount, SortRowsSum and CountRowsUnique
