The Power divergence family of statistics was introduced by Cressie and Read
\nin 1984. The likelihood ratio statistic and the Pearson\u2019s chi-squared statistic are
\nexamples of the many members of the power divergency family which are linked
\nthrough a family parameter \"\lmbda\". We present here the results of a comparative simulation
\nstudy on the accuracy of the chi-squared approximation for two members
