Let’s load the crimes data and look at the aggregated stats along with the distribution of criminals according to the region_name.

Now, let’s examine the density plots, scatterplots and correlation between public_houses and criminals.

Using the different variables available to us, let’s create multiple models starting from base model of using mean value. The t-stat of each variable included and the adjusted R-square parameters will help in decided the appropriate model for our usecase.

term	estimate	std.error	statistic	p.value	conf.low	conf.high
(Intercept)	153	6.55	23.3	1.57e-24	140	166

school_attendance	-0.0765	0.0356	-2.15	0.0381	-0.149	-0.00443

Let’s compare all these models to get a high level view on the best one.
