According to this table, considering one of the estimated values as zero and the remaining equal to the actual values results in a decrease in VAF and NSE. Similar to the correlation coefficient, the lowest values of the NSE and VAF (i.e., ˗0.67 and ˗0.48, respectively) are ...
The table contains critical values for two-tail tests. For one-tail tests, multiplyαby 2. If the calculated Pearson’s correlation coefficient is greater than the critical value from the table, then reject the null hypothesis that there is no correlation, i.e. the correlation coefficient is ...
Spearman’s correlation coefficient Spearman’s correlation coefficient is a statistical measure of the strength of a monotonic relationship between paired data. In a sample it is denoted by and is by design constrained as follows And its interpretation is similar to that of Pearsons, e.g. the ...
Pearson’s Correlation Coefficient • In this lesson, we will find a quantitative measure to describe the strength of a linear relationship (instead of using the terms strong or weak). A quantitative measure is important when comparing sets of data. • The strength of a linear relationship ...
Supplementary Table 5 Genes correlating to Senseless. n=948 wing disc cells. Correlation was calculated using Pearson’s correlation coefficient with one outlier removed. See Methods for details. Supplementary Table 6 Genes correlating to Wingless. n=948 wing disc cells. Correlation was calculated usin...

aInverse correlation between crawling and adhesion. N and M represent NRK and MDCK, respectively. The solid line is the result of curve fitting. The correlation coefficient was −0.82. The error bars are the propagated errors yielded by calculations using average speeds and their standard errors...
A VIF of, for instance, 4 indicates that in a regression including all variables of the analysis the standard error of the coefficient of this specific variable is two times (the square root of 4 is 2) as large as it would be if the variable was uncorrelated with the other variables. ...
Due to the modest sample size, the uncertainty on any individual correlation coefficient remains large. Examining the upper triangle of Table2, we find that the pairing ofLK,totandLX,ceis the strongest indicator of anti-correlation, with only a 1.8% chance of being zero or positive. As noted...
sinensis; the correlation coefficient was between 0.2 and 0.4. There was a very weak positive correlation between C. sinensis and C. militaris, with a correlation coefficient between 0.0 and 0.2. The results indicated that the bioclimatic environments of C. sinensis, C. gunnii and C. cicadae ...
