Chi or X is often used to abbreviate the name Christ, as in the holiday Christmas . When fused within a single typeface with the Greek letter rho , it is called the Chi Rho and used to represent the person of Jesus Christ.
The chi distribution describes the positive square roots of a variable obeying a chi-squared distribution. If , …, are independent, normally distributed random variables with mean 0 and standard deviation 1, then the statistic = =
By the central limit theorem, because the chi-squared distribution is the sum of independent random variables with finite mean and variance, it converges to a normal distribution for large . For many practical purposes, for k > 50 {\displaystyle k>50} the distribution is sufficiently close to a normal distribution , so the difference is ...
