Today my group and I worked to the final parts of our project report. Below are the findings that I contributed to the report:
- Permit Distributions over time
- From 2009 to 2010, there was a steep increase in the number of permits issued. There was also a drop in the number of permits from 2019 to 2020.
- Maximum number of permits are issued in October.
- When we check the permit trends by its status, the number of active permits is above 20000 since 2007. The trend of expire permits is between 10000 and 20000 with a downward trend since 2015 (although there are minor fluctuations where it increases).
- Since 2010, the largest number of permits issued was for ‘short form building permit’ followed by ‘Electrical Permit’.
- The highest frequency declared valuations is of the range $ -1000000 to 1000.
- The correlation of Sq_feet and declared valuations fluctuate a lot, but the highest correlation was between 2017-2019
- The Kruska-Wallis test shows that there is a statistically significant difference in permit durations between cities.
