Approximations to the chi-square distribution

Journal of Statistical Computation and Simulation, 1977
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 ...

A Uniqueness Property of the Chi-Square Distribution

Theory of Probability & Its Applications, 1996
Summary: We show conditions under which the chi-square statistic in the polynomial scheme is (up to a functional transformation) the unique statistic whose asymptotic distribution (when the number of observations grows to infinity) depends only on a one-dimensional parameter on the set of contiguous alternatives.

Computation of the Chi-Square and Poisson Distribution

SIAM Journal on Scientific and Statistical Computing, 1986
This paper is concerned with the computation of the tails of the chi- squared and Poisson distributions by recursive methods involving three base functions related to gamma-type integrals. The methods are applicable to most parameter values and their efficiency is demonstrated by a careful error analysis.
