- observed and expected are ranges or arrays of observed and expected values. They must have the same number of rows and columns and there must be at least 2 values in each.
- CHITEST calculates the χ2 statistic and degrees of freedom, then calls CHIDIST.
- returns approximately 0.969.
- The draft international standard ODFF calls this function LEGACY.CHITEST, and points out that it has limited mathematical validity. CHITEST is compatible with the Excel CHITEST function.
