As I know the chi square probability density function depends on Bessel function and at some values the Bessel function give negative values and the pdf also. How can I over come this problem or there is something I didn't under stand?

Thanks in advance

    Are you sure about the Bessel functions. I am not saying you are wrong, I just have never seen the connection. – user121049 May 18 '17 at 09:33
  • The chi-squared cdf is directly related to the incomplete Gamma integral, which is increasing. –  May 18 '17 at 09:53
  • I am talking about the probability density function of non central chi square distribution , it depends on the Bessel function of any kind according to the value of degree of freedom of the random variable . I tried the function on MATLAB and some values gives negative , which is wrong . thanks a lot – Samar Soliman May 22 '17 at 07:43
