@OptimisticCon Just combine all the counties in a region. Same difference for the most part.
If you had one odd country with high surrounded by low you could argue it's an outlier due to low denominator. But that's not what is happening most places.
@乐观主义者只是把一个地区的所有县合并起来。大多数情况下都是一样的。
如果你有一个奇怪的国家，高的被低的包围，你可能会说这是一个低分母的异常值。但大多数地方都不是这样。
