While the problem did not give any specific goal for decreasing the incidence of crime in the city, we determined that an effective and practical goal for the city is to reduce violent crime by 10% by the year 2020. In order to reduce the amount of crime in the city, we first created a model that calculated incidence of violence as a function of different data that we were given. We determined that some of the provided data had little to no impact on the amount of violent crime. Trying to incorporate this unhelpful information into our model would make it less accurate, so we developed a way to decide if a set of data was worth considering. When we applied this method to all of the sets of data, we were left with five that had a noticeable correlation with violence. These five values were City Population, High School Graduation Rate, High School Dropout Rate, Prison Population, and Percent of Parole Violations. With these five variables determined, we checked to make sure that each relationship with violence was roughly linear, then ran a multivariate linear regression to create a function that outputs an approximate incidence of violence given the City Population, High School Graduation Rate, High School Dropout Rate, Prison Population, and Percent of Parole Violations. When we tested this model against data that we already had, there was relatively low error, with discrepancies in incidence of violence ranging from 15 crimes to less than 1 crime.
