This program helps calculate agreement indices and medical diagnostic and decision-oriented indices for 2 x 2 classification tables. By running the mouse cursor over an output cell, users can access helpful hints. It is useful for teaching and looking at "what-if" scenarios. Agreement measures, 2x2 table, bookkeeping, cataloging, cooking, entertainment, healthcare, fitness, religion, astrology, shopping, sports, travel, weather.
This program calculates agreement indices and many medical diagnostic and decision-oriented indices for 2 x 2 classification tables.
Just run the mouse cursor over an output cell, and the hint will appear. More extensive information is available in the on-line help. It is recommended as a teaching-support utility for students etc.
Good for looking at "what-if" scenarios and the massive discrepancies that can sometimes be obtained between different measures of dichotomous agreement. Specifically, the program calculates the following measures of agreement from a 2x2 table
