Webb27 jan. 2024 · Correlation can take on any value in the range [-1, 1]. The sign of the correlation coefficient indicates the direction of the relationship, while the magnitude of the correlation (how close it is to -1 … Variations of the correlation coefficient can be calculated for different purposes. Here are some examples. The sample correlation coefficient r is not an unbiased estimate of ρ. For data that follows a bivariate normal distribution, the expectation E[r] for the sample correlation coefficient r of a normal bivariate is
The Pearson correlation coefficient (r) is the most widely used correlation coefficient and is known by many names: 1. Pearson’s r 2. Bivariate correlation 3.
