Imagine you are a retail company, and you want to generate synthetic data representing your sales orders, based on historical data. A rather difficult aspect of this is how to geographically distribute the synthetic data. The simplest approach is just to sample a random location (say a postal code) for each order, based on how frequent similar orders were in the past. For now, similar might just mean of the same category, or sold in the same channel (in-store, online, etc.) A frequentist approach to this problem usually starts by clustering historical data based on the grouping you chose and estimate the distribution of postal codes for each cluster using the counts of sales in the data. If you normalize the counts by category, you get a conditional probability distribution P(postal code∣category)P(\text{postal code} | \text{category})P(postal code∣category) which you can then sample from.
