Linear relationship in pearson correlation

The correlation coefficient ranges from −1 to 1. An absolute value of exactly 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line. The correlation sign is determined by the regression slope: a value of +1 implies that all data points lie on a line for which Y increases as X increases, and vice versa for −1. A value of 0 implies t… Nettet2 dager siden · Many of us rely on Pearson Correlation as part of the exploratory data analysis process, to identify relationships between feature inputs and the target… 57 comments on LinkedIn
