Feature Engineerin Jupyter Crime rate actually decreases as District populationincreases... Maybe fewer police officers per person,i.e. police are relatively understaffed? Crime rate increases significantly as Black pop %increases (because of over-policing). Crime Rate and Black Pop % follow extremelysimilar trend (would look better with 3 axes anddifferent colours, and maybe as a scatter plot...). Significant variation in crime count between Districts(provide T test).Also use this for Chicago Map. 4th of July seems to affect somecrimes - Battery increases, whileTheft, Narcotics and Prostitutiondecrease.Huge variation in Gambling -increases during summer. Prostitution increases around 7ammaybe because they're apprehendedafter leaving?Significantly different trends, seeingcrimes peak at different times of theday. Redistribute Dates inJupyter - FixingAnomalies N.B. Only full year data used, therefore 2017 not included.Sharp dip at 2004 - why? Possibly due to either change inpractice regarding crime reporting or an actual decrease incrime, due perhaps to introduction of policing initiatives, oran improvement in socioeconomic conditions. Slight increase at Friday - people going out - increasedlevels of socialisation as well as alcohol and drug intake.Slight decrease at Sunday because people tend to stay inand relax, therefore less opportunity for crime. Small peak at 12pm might be artificial -reporting officers default to the time outof convenience...Going to continue model-buildingwithout adjustment; in future, couldinvestigate reporting practices, thenjudge whether adjustment is needed.
