correlation的数值越接近1 或 -1,说明两组数据之间正向 或 反向 线性关联越强,但correlation总是要结合p-value一同考虑,才有意义。 样本点越接近虚线,关联性越好,correlation不因data scale而改变 同样的关联度,样本量增加,偶然性越低,p-value越小,才更有可信度 PS: 协方差corvariant 也是计算两组数据线性关系的...
In about half the cases, there is no bug. In the other half, the reported P value was smaller than the true P value. How much smaller? It depends on the number of XY pairs. This table shows the average discrepancy between the reported and true P value, and the chance that you would...

After calculation, a user-defined threshold of significance, e.g., p-value, that statistically shows whether or not the probability is greater in magnitude than t under the null hypothesis is introduced. Similar to PCC, the selection of the optimal threshold can be achieved by the cross-...
There are 90correlationcoefficients, so we have not listed them in Table 8.1. 5共有90个相关系数, 所以我们没有将它们列示于表格8.1中. 期刊摘选 This result is achieved by oil / oil or gas / gascorrelation. 通过石油/石油或天然气/天然气的对比便可得到这个结果. ...
A table of associated p-values (omitted for brevity) suggests very few p-values exceeding 0.05, implying that most coefficients are statistically significant. However, we do have nonrejection of ρqsec,drat = 0 and ρqsec,wt = 0, implying that these few relationships are statistically insignific...
(p-value < 5 × 10-8) in relation to the sleep traits in genome-wide association studies (GWAS) (n = 85,670 – 461,569). SNP lists were obtained from the relevant GWAS summary statistics available via the Sleep Disorder Knowledge Portal59. These were pruned for ...
No significant local rg was observed between APOE eQTLs and AD (FDR < 0.05), although a nominal positive rg was observed in blood (ρ = 0.178, ρ CI = 0.007 to 0.352, p = 0.039; Supplementary Fig. 5e, Supplementary Table 7). Overall, these results indicate that risk...
(Fig.2). The interface displays a histogram of genome-wide correlation values (Pearson’s R and associated p value) with a linked data table for interactive exploration (Fig.2a). The interface also shows the corGSEA results with a linked figure and searchable data table layout (Fig.2b, c...
Step 1:For each ETF, we identified its correlation with all other ETFs in the correlation table. For example, for the S&P 500 large-cap ETF (IVV), we have to find its correlation with the others. Here's IVV with the others:
