论文摘要
我们提出了基于共同购买的相关性的产品替代性的度量，该产品可以迅速计算并且易于解释。在对药店零售链的实证研究中，我们证明了其特性，将其与产品互补性的类似简单度量进行比较，并使用它来找到少量的替代品。
We propose a measure of product substitutability based on correlation of common purchases, which is fast to compute and easy to interpret. In an empirical study of a drugstore retail chain, we demonstrate its properties, compare it to a similarly simple measure of product complementarity, and use it to find small clusters of substitutes.
