Correlation between two distributions

WebViewed 80k times 46 I know that for the 2 -dimensional case: given a correlation ρ you can generate the first and second values, X 1 and X 2, from the standard normal distribution. Then from there make X 3 a linear combination of the two X 3 = ρ X 1 + 1 − ρ 2 X 2 then take Y 1 = μ 1 + σ 1 X 1, Y 2 = μ 2 + σ 2 X 3 WebApr 6, 2024 · The pairs plot builds on two basic figures, the histogram and the scatter plot. The histogram on the diagonal allows us to see the distribution of a single variable while the scatter plots on the upper and lower triangles show the relationship (or lack thereof) between two variables.

Correlation (Pearson, Kendall, Spearman)

The degree of dependence between variables X and Y does not depend on the scale on which the variables are expressed. That is, if we are analyzing the relationship between X and Y, most correlation measures are unaffected by transforming X to a + bX and Y to c + dY, where a, b, c, and d are constants (b and d being positive).
