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:

Issues:

  • The draft international standard ODFF calls this function LEGACY.CHIDIST, and defines a new CHISQDIST function. * CHISQDIST is expected for OOo 3.1
  • The draft international standard ODFF has no restriction for x, but defines that LEGACY.CHIDIST returns 1 for x ≤ 0.


Example:

CHIDIST(2; 3)

returns approximately 0.5724.
