CHITEST
Returns a measure of χ^{2} 'goodness of fit'.
Syntax:
CHITEST(observed; expected)
- 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 χ^{2} statistic and degrees of freedom, then calls CHIDIST.
Example:
CHITEST({8;9;7;8}; {8;8;8;8})
- returns approximately 0.969.
Issues:
- 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.
