What hypotheses do we want to test?

[EricRoche]

• [ ] What types of violations occur together?
• [ ] What types of violations do not occur together?
• [ ] How have neighborhoods trended over time?
• [ ] What's the best way to classify or group neighborhoods?
• [ ] Which neighborhoods have improved?
• [ ] In neighborhoods that have improved, were there "keystone" violation types?
• [ ] Does the presence of a certain type of violation predict another type of violation will occur in the near future?
• [ ] How do the different types of violations affect how long a case takes to close?
• [ ] Is the timeframe to resolve certain types of violations the same across the City?
• [ ] How do code violations effect property values?
• [ ] What types of code violations are associated with dangerous buildings?
• [ ] Can we find a relationship between crime data and code violations? If so, what comes first?

Are dangerous buildings at high risk for arson?

What is the best way to classify violation types? Ordinance Chapter is a good coarse-grained classification, but is description too fine-grained? Ordinance Number might work, but would have to be decorated with some added descriptive text. The right level of classification granularity may also differ depending on the question we are trying to answer.

[EricRoche]

• [ ] Does an increased presence of property violations negatively impact property assessments?
• [ ] What types of property violations are more likely to decrease property values?
• [ ] What is the tipping point for a property or a neighborhood between good/bad neighborhoods
• [ ] Over time property violations trends within geographic areas - what is happening in neighborhoods (layer in demographic/socio-economic data).
• [ ] How does language spoken effect time to resolve a violation?
• [ ] What is the correlation between citizen satisfaction and code violations? What kind of property violations are causing dissatisfaction?
• [ ] How do 311 reports of violations report to property violations found?
• [ ] If property violations are a predictor of a certain type of crime, what are the timeframes around it?
• [ ] Does the demolition of dangerous buildings result in fewer code violations in that neighborhood or that property?
• [ ] What happens to a demolished dangerous building lot?

What day of week are violations most likely to be recorded? What day of week are violations most likely to be closed? Which seasons correlate to higher frequencies of each type of violation?
