标题: 求: 比例检验的精确方法的详细公式
minitab中
单、双、多比例检验的精确方法的详细公式；
单、双Poisson率的精确计算方法的详细公式；

最好是有Excel的计算公式，标准下载统计插件升级时就会加入这些功能，方便大家使用！

重赏了，知道一个给1000金币

目前最缺单比率检验的精确算法的p值的公式, 看看谁能找到?

单比例检验的精确方法的详细公式:
Hypotheses
The null hypothesis for a 1 proportion test is: H0: p = p0 where

· p = the population proportion

· p0 = the hypothesized proportion

You can choose any one of three alternative hypotheses:

H1: p > p0
One-tailed test

H1: p < p0
One-tailed test

H1: p p0
Two-tailed test

Confidence interval
Lower limit (PL) =
n1 * F

n2 + n1 * F

where

n1 = 2x
n2 = 2 (n - x +1)
x = number of events
n = number of trials
F = lower a/2 point of F with n1 and n2 degrees of freedom

Upper limit (PU) =
n1 * F

n2 + n1 * F

where

n1 = 2 (x + 1)
n2 = 2 (n - x)
x = number of events
n = number of trials
F = upper a / 2 point of F with n1 and n2 degrees of freedom

The interval (PL , PU) is an approximate 100 (1 - a)% confidence interval of p.

Note: When x = 0 or x = N, Minitab calculates only a one-sided confidence interval.

where:

= observed probability, = x / n, where x is the observed number of events in n trials

p0 = hypothesized probability

n = the number of trials

等等....Minitab帮助里面的“另请参见”里面有详细的公式啊

这个F是指什么？

呵呵，估计很少有人知道这个公式的，我帮助鹰蛇老师查查吧，
