why we need the average nearest neighbor analysis before the hot spot map

[YasserHassan]

 If we run the Hot Spot analysis only and the results showed hot and cold spots, does that mean that the points are clustered without doing the nearest neighbor analysis?

[DanPatterson_Retired]

Don't interchange nearest neighbor with hot spot.  The former is a statistical test which assesses statistically whether the perceived distribution is statistically significant... the latter provides no such measure.  In short, don't believe your eyes since what you see may be purely by chance
