type ChiSquareDistribution =
The sum of the squares of n indepemdent normal
variables with zero mean and unit variance has a
chi-squared distribution with n
degrees of freedom. This means it also describes the
Variance of samples taken from a
From this last property, we can see the usefulness
of the chi-squared distribution as a test of statistical
significance. We can determine the likelihood of obtaining
a sample that deviates from the expected value by a
The sum of two or more variables that have
a chi-squared distribution also has a chi-squared
distribution. The number of degrees of freedom of the new
distribution equals the sum of the degrees of freedom
of the original distributions.
