How it works

The Data

Prices per square foot for the zipcodes in SF over time are from zillow, and crime data over time is from the SF open data.

The Model

Using pricing data for each of the zipcodes in San Francisco and crime data from the San Francisco open data I built a logistic regression model, making a prediction about whether or not a given zipcode area will beat the market.

Beating the market is defined as having a rise in price per square foot that is above the average rise for San Francisco.

As predictors I use normalized percentage of crime and crime type, looking at the crime occurring a year prior to the predicted year.

Using 21 features the model reaches over 65% accuracy.
