Abstract
The chi-square distribution arises frequently in applied statistics.Associated with the chi-square random variable with v degrees of freedom are two interdependent variables: the probability integral and the percentage point.Given one of these variables,the other can be obtained from chi-square tables for selected values.In order to overcome the inconvenience of statistical tables and interpolation,many approximations have been suggested.The computational difficulty and accuracy of various approximations is compared.
