Earth mover distance in r
WebSep 6, 2024 · The Earth Mover’s Distance is the minimum amount of work involved, where “amount of work” is the amount of earth you have to move multiplied by the distance you have to move it. The EMD can also be shown to be equal to the area between the two empirical CDFs. The EMD is a good tool for distributions with long tails. WebOct 16, 2024 · Earth Mover’s Distance (EMD) Kolmogorov Smirnov Test (KS Test) PSI The PSI metric has many real-world applications in the finance industry. It is a great metric for both numeric and categorical features where the distributions are fairly stable. Equation:PSI = (Pa — Pb)ln (Pa/Pb)
