Here is the link to the data dictionary. If anything is wrong with it, please let me know. https://docs.google.com/spreadsheets/d/1tL11Ce6x_jYo3aitxbalo_NcoHaZ6o1CxQUHeHTUIDM/edit?usp=sharing

• Utilized the old dataset (from department of finance) for data cleaning, dropped NAICS column for accuracy.
• Performed EDA and figured out business survival analysis would give better data insights from the given data set.
• Created a new column 'duration' which helps in analyzing patterns in business closures and identify key factors that contribute to business success or failure.

An additional resource to add to resources. The following is a listing of business that register with Office of Finance during that month: https://finance.lacity.gov/new-monthly-business-listings

[rahul897]

• Performed EDA by filtering the data on multiple levels namely - city, active, inactive, inactive during covid (2020-2022)
• Created heatmap based on real Map to see if actual locations have any relevance
• Figured out inactive businesses along the different categories based on NAICS column. notebook for reference: https://colab.research.google.com/drive/1KqMzxy96pF4Jh8IqcD9zk5f28BkBZzLa?usp=sharing
