令P(u,x)表示正则化不完全伽玛函数,可以看出,对于每个α≥0,P(x,x+α)随着x在正实半轴上的增大而减小,并且当x趋于无穷大时P(x,x+α)收敛于1/2。探讨了这些结果的统计显着性。
Letting P (u, x) denote the regularised incomplete gamma function, it is shown that for each α ≥ 0, P (x, x+ α) decreases as x increases on the positive real semiaxis, and P (x, x + α) converges to 1/2 as x tends to infinity. The statistical significance of these results is explored.
