Robbery incidents can predict violence incidents and visa versa

This is the graph and map following the methodology of the previous post. The correlation is almost exactly the same as the robbery data arrays at 0.55 and 0.67 when the two West End outlier wards are removed. This raises the intriguing possibility that robbery incidents can predict violence incidents and visa versa.

Sure enough as the graph above shows a high level of predictability between the two incident categories. The correlations are 0.86 for all the Wards and actually goes down to 0.82 if the West End wards are removed. There are interesting aspects to this graph. Even though there is very high predictablity/correlation overall those seven Wards that have between 6 and 8 violence z scores appear to have a very low level of robbery predictability.
