您希望根据适合自己业务的参数来对用户进行细分，以这种方式为自己的电子商务网站创建新的受众群体，比如已购买过商品的用户群体。下面哪种方法可让您得到一个预测性受众群体？

The correct answer is "You create an audience that includes users who are likely to make a purchase in the next 7 days" because a predictive audience specifically uses machine learning to identify users who are likely to perform a future action, such as purchasing. This aligns with the goal of segmenting users based on parameters suitable for a business, like identifying potential buyers. The other options describe retrospective or behavioral audiences, not predictive ones: "You create an audience that includes users who started checkout but didn't complete a purchase" identifies users based on past behavior (abandoned cart). "You create an audience that includes users who added items to their wishlist" identifies users based on past behavior (wishlist addition). "You create an audience that includes users who purchased in the last 30 days" identifies users based on past behavior (previous purchasers).
