26.03.2015 · I'd like to use R to find the critical values for the Pearson correlation coefficient. This has proved difficult to find in search engines since the standard variable for the Pearson correlation coefficient is itself r.In turn, I'm finding a lot of r critical value tables (rather than how to find this by using the statistical package R).. I'm looking for a function that will provide …

Correlation Coefficient is a method used in the context of probability & statistics often denoted by {Corr(X, Y)} or r(X, Y) used to find the degree or magnitude of linear relationship between two or more variables in statistical experiments. It is a ratio of covariance of random variables X and Y to the product of standard deviation of random variable X and standard deviation of random ...

and this value of \(r_c\) is the so called critical correlation value used to assess the significance of the sample correlation coefficient \(r\). These critical correlation values are usually found in specific tables.
For example, with n = 28, v = 28 - 2 = 26, and the critical value is 0.374 at a = 0.05 significance level. Thus, an observed r = 0.31 in a sample of n=28 ...
