However, the greater the degrees of freedom, the more the chi square distribution looks like a normal distribution. A chi-bar-squared distribution is a mixture of chi-square distributions, mixed over their degrees of freedom. You’ll often find them when testing a hypothesis with an inequality...

To create a 2 D Gaussian array using the Numpy python module. My rule of thumb is to use $5\sigma$ and be sure to have an odd size. A reasonably fast approach is to note that the Gaussian is separable, so you can calculate the 1D gaussian for x and y and then take the outer p...
