CoP: Data Science: Analyze correlations between metro locations and 311-data requests

[ryanmswan]

Overview

Investigate whether there are meaningful trends associated with metro stops and metro lines with regards to requests tracked by 311-data in LA County.

Action Items

• Define requirements for 311 data (adding notes to the resources section and discussing at the Data Science CoP meeting
  • Do you need a one-time or ongoing dump of the data?
  • Do you need subset of data (i.e. certain years) or the entire data set (approx. 4 million rows or 11 GB)?
    • If a subset is needed, please define subset characteristics (i.e. date range, etc.)
  • Do you need online access via an API or a download of data?
  • Add dependency label and put in the icebox until 311 data is provided
• Find available data sources and add to Resources section below
• Determine is this is one-time or ongoing project (and assign appropriate label)
• Write one-sheet
  • Define stakeholder
  • Summarize project including value add
  • Define project 6 month roadmap
  • Detail history (if any)
• Define tools to be used to visualize combined data
• Create issues for the following
  • EDA (Exploratory Data Analysis) of metro data
  • Identify correlations between distance from metro stop and request type
  • Determine if correlations observed are solely due to metro stop or are more broadly associated with population density or other factors
  • Combine geolocation data for metro lines with district types
  • Compare correlations/trends between different districts within each type
  • Compare LA county data with other California counties, compare with district types within county. (Post MVP)
  • Compare with statewide trends and within district types. (Post MVP)
