alpha是一型错误概率 beta是二型错误概率 alpha和1-beta说的都是拒绝零假设 拒绝域如何选取: 一般,alpha减小beta会增加,假设检验两个目标: 1. H0为真时,以最小可能性拒绝H0 2. H0为假时,以最大可能拒绝H0 所以在固定大小的alpha点集中,拒绝域通常是1-beta最大值对应的样本点的集合 3.检验的p值 p value是...
beta分布与伯努利分布不同的地方在于，伯努利可以描绘discreate value，beta分布描述的是连续性的取值区间（...
I’ve conducted this ANOVA on R and XLStat and the outputs for the F fisher, p-value, coefficient estimations, t-values, std error … are exactly the same. However, XLstat offers an extra output : the standardized coefficients (called too beta coefficients). Firstly, I was surprised, bec...
The beta value provided on Google Finance may differ from the beta on Yahoo Finance or Reuters because of the various ways to estimate beta. Multiple factors, such as the time duration of the period, are included in the computation of the beta, which creates varying results. Some calculations...

As a result, it allows assessing the power function as a function of 𝛿δ only for a given value of n. In Figure 1, we plot the power of the suggested test as a function of 𝛿δ for 𝑛∈{60,120,250,500}n∈{60,120,250,500}. We observe that even for a small sample size...
Underneath each γ value, a λ value, as per the t-statistics, is given in (); here, * = 10% significant level, ** = 5% significant level, and *** = 1% significant level to accept or reject null hypothesis. In panel A, when the beta is replaced with the skewness and co-...
