## How to simulate Chi-squared distribution

Is there any algorithm to simulate Chi-squared distribution?
Here, the degrees of freedom is very large. It may be 10^8.

 Recognitions: Science Advisor The Central Limit Theorem says that chi-squared approaches a normal distribution when the number of DOF's k becomes large. A normal distribution is an excellent approximation for k>50 in most cases, so it should be near perfect for k=10^8.
