Histogram

Introduction

The values are centered and reduced. We need to analyse their distribution for a futur analysis based on a semi parametric statistic approach. On this case , I give all the distribution for all the variables.
Sometimes values are difficult to identify and two methods (mlc and em) are used to identify their distribution.
We can see by example that the more representative population of each community are based on low population number. We can see that the white people representation are more represented in this study. Black, asian,hispanic are lowly represented in the study. 
We can see too than the urban people or illegitime children or not english speaking or immigrant or poverty are poorly represented. While their impact are really important in the violent crimes factor.
