扩展的肯达尔τ系数表及有关递推公式

Extensive Kendallτ Coefficients Table and its Recurring Formula

通过对 n元排列中逆序数为 k的排列个数及最值的讨论 ,得到了有关的递推公式。由此将数理统计中常用的肯达尔 τ系数临界值表从 n=1 0扩展到 n为任意自然数的情形 ,并特别给出了 n=2 0情形下的 τ系数临界值表 ,扩大了

Through the study of the numbers of permutations and maxim which have the same reverse order , we get the recurring formula,with which we can extend the Kendall τ cofficient table which is frequently applied in mathematical statistics in the condition of any natural number. Specifically, we have got τ cofficient table in the condition of n equals to 20 in this paper, so that the practical extend of independence test can be enlarged.
