CHIDIST
Calculates values for a χ2-distribution.
Syntax:
CHIDIST(x; k)
- k is the (positive integer) degrees of freedom for the χ2-distribution.
- x is a number >=0.
- CHIDIST returns the right tail probability for the χ2-distribution:
Example:
CHDIST(2; 3)
- returns approximately 0.5724.

Issues:
- The draft international standard ODFF calls this function LEGACY.CHIDIST, and defines a new CHISQDIST function.
