However, in the forward written analysis to avoid confusion we will still term hardship as low when living conditions are good! as the term is used and normally enterpreted] First of all it is observed that none of the values are just above 0.85 for theft per capita income and the closest to zero value is 0.009 for other offence/Prc. of housing crowded. When reviewing these numbers common accepted norms are used (Hinkle 2003). The standards used can be seen in table 2. Size of Correlation Interpretation .90 to 1.00 (−.90 to −1.00) Very high positive (negative) correlation .70 to .90 (−.70 to −.90) High positive (negative) correlation .50 to .70 (−.50 to −.70) Moderate positive (negative) correlation .30 to .50 (−.30 to −.50) Low positive (negative) correlation .00 to .30 (.00 to −.30) negligible correlation Table 2 Many results and consideration can be highlighted from this matrix. Since hardship is a general indicator. It becomes visible that more incidents of theft, crimital thresspass and deceptive practices (illigal trade) occur in areas where hardship is at lower levels. Especially theft and deceptive practices have High possitive correlation (0.77, 0.86). This may be enterpreted as more of these crimes occur in areas with more money, as can be seen on the Per Capita Income attribute, which has similar correlations as hardship e.g. the results seam to suggest that low income by area is a good indicator for hardship by area. Among high negative correlations it becomes aparent that the act of battery and weapons violation is less frequent in rich areas and areas with better socioeconomic conditions (-0.76, -0.81). It is interesting how burglary and theft is not alligened in terms of socioeconomic correlation. The analysis seams thus to suggest that burglary is much more independent of socioeconomic backgrounds and occurs in all layers of society represented by districts. While theft very specificly only seam to correlate when there is wealth present. That may seam intuitive, as in the thieves are drawn to the money, but assumptions could be made that the rich also guard their houses and valuables better and thus burglary spreads accross society. Finally the analysis might highlight the results of weapons violations which draws a distinct picture that percent households in poverty and unemployment (0.736822, 0.799575) has high correlation with unlawful behavior for possession and use of weapons. Oppositely low levels of hardship, e.g. good life conditions seams to strongly attribute against being exposed to weapons violations (-0.818258). We can indeed see that this is the case of southside Chicago, where Katana was born and raised.2e:T10c4,To gain a deeper intuitive understanding of our socioeconomic factors we used the Apriori algorithm to compute rules, or configurations of one or more variables that strongly imply a configuration for another variable. These rules can be thought of as analogues to the reasoning of how items in a supermarket are shelved - customers that purchase cereal usually purchase milk, but customers that purchase cereal may or may not necessarily purchase broccoli. So, the supermarket capitalizes on customer purchasing habits by storing cereal and milk near each other. Looking at the socioeconomic factors in Chicago, it's easy to assume that factors like lower incomes and higher unemployment predict higher hardship. Running our data through the Apriori confirmed some such rules, and generated some surprises. To utilize the Apriori algorithm, we first need to preprocess the data. This is done binarizing all continuous variables according to their median value. For example, if the median value of one variable is 0.5, then all instances where the variable is less than 0.5 are classified as zero, and all other instances are classified as 1. The binarized data is then transformed into a list containing the label names of whether a given variable is ‘on’ or ‘off’ using the provided mat2transactions function. This list is then fed into the provided apriori algorithm function. It's worth mentioning that our socioeconomic data set is very small, so these rules should really be treated more like suggestions. However, some predicted rules (see table) were consistent with our data analysis, so this proved a worthwhile overview. Some interesting rules are presented and discussed below. Socioeconomic Factor(s) Result Support Confidence % OF HOUSEHOLDS BELOW POVERTY (HIGH), HARDSHIP INDEX (HIGH) PER CAPITA INCOME (LOW) 0.416 0.970 % OF HOUSEHOLDS BELOW POVERTY (LOW) HARDSHIP INDEX (LOW) PER CAPITA INCOME (HIGH) 0.416 0.941 % AGED 16+ UNEMPLOYED (HIGH) HARDSHIP INDEX (HIGH) PER CAPITA INCOME (LOW) 0.403 0.969 PER CAPITA INCOME (LOW) HARDSHIP INDEX (HIGH) 0.481 0.949 % AGED 25+ WITHOUT HIGH SCHOOL DIPLOMA (LOW) % OF HOUSING CROWDED (LOW) 0.429 0.846 (LOW) and (HIGH) signify whether the binarized variable is treated as 0 or 1, respectively. This analysis was done before inverting the hardship rating. So, higher hardship implies worse socioeconomic conditions and lower hardship implies better conditions. From the rules, we find the best rules for predicting per capita income. We transcribe the first two rules: if the percentage of households below the poverty line exceed the median percentage of households under the poverty line, and the district's hardship index is above the median hardship index, we can say with ~95% assurance that the per capita income of the district will fall below the median per capita income across all districts. The converse of this rule is also true; this implies a circular generation of rules from the Apriori algorithm. Another indicator of low per capita income is high unemployment combined with high hardship. Intuitively this makes sense, as areas with high unemployment typically suffer economically. Combining high unemployment with a 'hard' district, one can claim with 96% certainty that the district is below the median per capita income. The overall best indicator for hardship index was found to be 'Per capita income'. The best indicator was found by finding the maximum sum of the support and confidence values for rules predicting hardship index. Combining the support and confidence values ensures the greatest 'spread' across the data set to purport an actual rule instead of coincidental pairings. This rule makes sense, and it's interesting that the overall best indicator for 'hardness' of a district is the amount of wealth the district has. The final rule was unexpected. One would think that graduating from high school wouldn't correlate too heavily with whether or not one lives in a crowded home. It makes sense that, if one graduates from high school, then they are more likely to eventually move somewhere away from home compared to someone who did not graduate. It's possible that this rule could be misattributed due to the low quantity of data, but it nonetheless provides an interesting thought.2f:T7b2,chart = { var margin = {top: 0, right: 30, bottom: 30, left: 30}, width = 700 - margin.left - margin.right, height = 700 - margin.top - margin.bottom;
