Remarks
The χ 2 distribution is associated with a χ 2 test. Use the χ 2 test to compare observed and expected values.
For example, a genetic experiment might hypothesize that the next generation of plants will exhibit a certain set of colors. By comparing the observed results with the expected ones, you can decide whether your original hypothesis is valid:
If either argument is nonnumeric, ChiSq_Dist_RT generates an error.
If x is negative, ChiSq_Dist_RT generates an error.
If degrees_freedom is not an integer, it is truncated.
If degrees_freedom < 1 or degrees_freedom > 10^10, ChiSq_Dist_RT generates an error.
ChiSq_Dist_RT is calculated as ChiSq_Dist_RT = P(X>x), where X is a χ2 random variable.
