ECI correlation with diversity about py-ecomplexity HOT 4 CLOSED

Hi Max,

In what follows I assume that you are computing the ECI based on a matrix of municipalities and the prevalence/presence of crimes of different types across those municipalities. Is this right?

To your question "Do you know if exist a math assumption or equation so we can ensure that the ECI should be always positive correlated with diversity?", the answer is no. There is no equation that says that ECI should be positively correlated with diversity. This is because there is no "first principles" derivation (yet) of the ECI that guarantees that it is a mathematical object that actually estimates statistically such a thing like "complexity". We know what eigenvectors do in general, but the latter issue of formally linking the concept of complexity to one specific eigenvector of a specific type of matrix is a still current open research problem.

Having said that, let us assume that ECI does indeed quantify something like "economic complexity", i.e., let us assume that it magically estimates the number of capabilities present in a city. Then, why is it surprising to you that most diverse places are also the places that have the highest "criminal complexity index"? The most diverse cities may also be diverse regarding the "criminal knowhow" available to criminals. Thus, they can recombine all this criminal knowhow in more ways, and commit not only more crimes, but also more different types of crimes, and more "complex" and "sophisticated" crimes. Or maybe I misunderstood your question...?

Thank you Matias for your quick response. I will wait for any notice. Thank you again.

Hi Andres,

First of all, thank you for your reply. Yes, I am using a municipality matrix and the associated crime. I already created the program and calculated an index. The program also satisfy that higher crime diversity will be associated with higher crime "complexity". As you mention, some places acquire capabilities to produce more complex crime related to the diversity. I was worry if I was missing something in between. So your answers clarify the issue.

Thank you.
