When this is the case, some say significant correlations are likely to replicate because the relation between two variables must be robust enough to be detected even with low statistical power. Others say that significant correlations in the context of small sample sizes are not likely to ...

If the correlation between two variables is statistically significant, does that imply that the correlation is also large in magnitude? If the coefficient of correlation = 0 .80, the variances of X and Y are 2 and 5, respectively. Then Cov(X, Y) must be?

aIn that case, it can be shown that R2 and βˆwill be random and that the usual t -statistic will diverge, giving rise to seemingly significant correlations between variables that are unrelated by construction. 案件,它可以显示R2和βˆwill是任意的,并且通常t -统计将分流,提升表面上由建筑是...
Explain what is meant by a correlation between two variables, how one would know if a correlation coefficient were weak or strong, and what constitutes a perfect relationship; and describe what is meant by positive, negative, and zero correlatio...
Hi, I want to visualize a correlation matrix using a correlogram with the "corrplot" command. However, I only want to picture significant correlations between a set of explanatory variables and response variables. How can I do that? 0 Comments ...
how approximate randomization tests can evaluate (a) the number of significant correlations between a single variable and a large number of other variables, (b) the number of significant correlations between two large sets of variables, and (c) the average size of a large number of effects. ...
Correlation is a measure of the magnitude and direction of the relationship between two variables. Correlation is often calculated in the beginning stages of regression analysis, along with the creation of a scatterplot to assess the linearity of th...
