Simple matching coefficient python
Webb6 mars 2024 · The simple matching coefficient (SMC) or Rand similarity coefficient is a statistic used for comparing the similarity and diversity of sample sets. [1] Given two objects, A and B, each with n binary attributes, SMC is defined as: SMC = number of matching attributes sum of all attributes = M 10 + M 01 M 00 + M 11 + M 01 + M 10 where: WebbGower’s similarity coefficient; it is appealing because ranges between 0 and 1, being an average of the scaled distances calculated variable by variable. In addition, the Gower’s distance handles missing values and allows for a user-defined weighting scheme when averaging distances. The
