WebbThe correlation coefficient ranges between -1 and +1. When the correlation is equal to 1, this indicates that there is a perfect lineal association between the two variables. A correlation coefficient equal to -1 indicates that there is a … WebbI know that asymptotic distributions could lead to biased estimators of linear regression. But Pearson coefficient is the way to calculate, it is not an estimation of something, so I cannot say if it is biased or non-biased. I know that if the relationship is linear then you get a strong Pearson coefficient, and if not then you get a small number.
WebbThe Pearson correlation coefficient can be seen as a mean-centered cosine similarity, and is defined as: pearson_sim ( u, v) = ∑ i ∈ I u v ( r u i − μ u) ⋅ ( r v i − μ v) ∑ i ∈ I u v ( r u i − μ u) 2 ⋅ ∑ i ∈ I u v ( r v i − μ v) 2 or WebbPearson correlation coefficient, also known as Pearson R, is a statistical test that estimates the strength between the different variables and their relationships.
