Web8.) There are many measures for assessing similarity and dissimilarity. In general, such measures are referred to as proximity measures. You can think of the proximity of two objects as a function of the distance between their attribute values, although proximity can also be calculated based on probabilities rather than actual distance. WebThe 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: where: is the total number of attributes where A and B both have a value of 0.
