通过把所得到的统计检定值,与统计学家建立了一些随机变量的概率分布(probability distribution)进行比较,我们可以知道在多少%的机会下会得到目前的结果。倘若经比较后发现,出现这结果的机率很少,亦即是说,是在机会很少、很罕有的情况下才出现;那我们便可以有信心的说,这不是巧合,是具有统计学上的意义的(用统计学的...
长尾分布(Long-tailed Distribution) 长尾分布( )是统计学和概率论中的一个重要概念,用于描述一组数据中尾部(即远离均值的部分)包含了相对较多极端值的情况。以下是对长尾分布的详细解释: 定义 长尾分布是重尾分布的一个子类型,其特点是分布的尾部较长,即存在大量的极端值。这些极端值在分布中的出现概率较低,但它...
The FDIST function returns the (right-tailed) F probability distribution (degree of diversity) for two data sets. You can use this function to determine whether two data sets have different degrees of diversity.
Comparing the variance of two waves using a two-tailed hypothesis To run the test execute the command: StatsFTest/T=1/Q data1,data2 The results of the test appear in the F-Test table: n1 100 Mean1 99.8754 Stdv1 3.39174 degreesOfFreedom1 99 n2 80 Mean2 79.6029 Stdv2 3.10709 degrees...
rticle describes the formula syntax and usage of the F.DIST.RT function in Microsoft Excel. Returns the (right-tailed) F probability distribution (degree of diversity) for two data sets. You can use this function to determine whether two data sets have
Returns the inverse of the right-tailed F probability distribution. If p = F_DIST_RT(x,...), then F_INV_RT(p,...) = x. C# 複製 public double F_Inv_RT (double Arg1, double Arg2, double Arg3); Parameters Arg1 Double Probability - a probability associated with the F cumulative...
Distribution: FRatio(9,9) Computed Statistic: 1.48175182481752 Computed p-value: .283683963290489 Confidence Interval: .4661219412315 .. infinity (ratio of population variances) Result: [Accepted] This statistical test does not provide enough evidence to conclude that the null hypothesis is false. ...

Returns the right-tailed F probability distribution. You can use this function to determine whether two data sets have different degrees of diversity. For example, you can examine the test scores of men and women entering high school and determine if the variability in the females is different ...
For neutralization titer analysis, groups of animals were compared on the distribution of the neutralization titer outcome using the Mann-Whitney test (Fig. 6A) or two-sample t-test (Fig. 6E). Groups consisted of ten animals except one animal that was excluded from the DT-preF group in the...
