However, this condition is clearly defined in " regression or connection between two or more things ". A more formal definition says, " Correlation is a statistical method used to assess a possible association between two or more variables ". In statistics, correlation is an indispensable tool that forms the basis for in-depth statistical analysis like forecasting, ...

It is useful to note that correlation forms the basis for simple bivariate linear regression. The slope coefficient is simply (10)b1=rxyΣ(Y−μy)2Σ(Y−μy)2, and the intercept is calculated as b0 = Y¯; − b1X¯. Interpretation of Pearson's r As noted, the correlation coe...
