`scipy.special.``chdtrc`(v, x) = <ufunc 'chdtrc'>

  Chi square survival function

  Returns the area under the right hand tail (from x to infinity) of the Chi square probability density function with v degrees of freedom:

      1/(2**(v/2) * gamma(v/2)) * integral(t**(v/2-1) * exp(-t/2), t=x..inf)
