2021-10-17 · The Pearson correlation coefficient is computed as: As we can see, the correlation coefficient is just the covariance (cov) between 2 features x and y "standardized" by their standard deviations (σ), where. the standard deviation is computed as. Similarly, the covariance is computed as. In our simple example above, we get. cov(x, y) ≈ 1.3012

Correlation. The Pearson correlation coefficient, r, can take on values between -1 and 1. The further away r is from zero, the stronger the linear relationship between the two variables. The sign of r corresponds to the direction of the relationship. If r is positive, then as one …

The Pearson correlation coefficient rXY is a measure of the strength of the linear relationship between two variables X and Y and it takes values in the closed interval [−1, +1]. The value r XY = +1 reflects a perfect positive correlation between X and Y, whereas the value r XY = 0 indicates that no correlation can be found (based on the ...
