很遗憾,该数据集不包含名为 bike owner 的列。不过,该数据集确实包含一个名为 recently bought a bicycle 的列。
对于此模型,recently bought a bicycle 是合适的代理标签还是不合适的代理标签?
代理标签良好
recently bought a bicycle 列是一个相对较好的代理标签。毕竟,现在购买自行车的大多数人已经拥有自行车。不过,与所有代理标签一样,即使是效果非常好的代理标签,recently bought a
bicycle 也无法做到尽善尽美。毕竟,购买商品的人员并不一定是使用(或拥有)该商品的人员。
例如,人们有时会购买自行车作为礼物。
代理标签不当
与所有代理标签一样,recently bought a bicycle 并不完美(有些自行车是作为礼物购买的,并赠送给他人)。不过,recently bought a bicycle 仍然是判断用户是否拥有自行车的相对较好的指标。
