Function Documentation

float ChiSquaredProbability ( double  chiSquared,
double  nrDOF 
)

Returns the probability that an observation, correctly described by a model with nrDOF, will give rise to a chi-squared larger than the one observed; from this, one can interpret this probability as how likely it is to observe as high (or higher) a chi-squared. source: Numerical Recipes
