WebApr 11, 2024 · The correlation coefficient for a perfectly negative correlation is -1. 2. Negative Correlation (-1≤ r <0) A negative correlation is any inverse correlation where an increase in the value of X is associated with a decrease in the value of Y. For a negative correlation, Pearson’s r is less than 0 and greater than or equal to -1.
The square of the sample correlation coefficient is typically denoted r and is a special case of the coefficient of determination. In this case, it estimates the fraction of the variance in Y that is explained by X in a simple linear regression. So if we have the observed dataset and the fitted dataset then as a starting point the total variation in the Yi around their average value can be decomposed as follows WebJan 25, 2024 · Karl Pearson’s Coefficient of Correlation.
