## Function Chi-Square-Significance

(

**chi-square-significance** < x > < dof > )

Computes the complement of the cumulative distribution function for a

Chi-square random variable with ` dof' degrees of freedom evaluated at `

x.' The

result is the probability that the observed chi-square for a correct model

should be greater than ` x.' The implementation follows Numerical Recipes in C,<br> section 6.2. Small values suggest that the null hypothesis should be rejected;<br> in other words, this computes the significance of `

x.'
