k is the (positive integer) degrees of freedom for the χ²-distribution.

Issues:

• The draft international standard ODFF calls this function LEGACY.CHIDIST, and defines a new CHISQDIST function.
• The draft international standard ODFF has no restriction for x, but defines that LEGACY.CHIDIST returns 1 for x ≤ 0.
