Zillow publishes a variety of cool data that I haven’t explored much yet. The first dataset that caught my eye was the Zillow Home Value Index (ZHVI). Zillow describes it as the “smoothed, seasonally adjusted measure of the typical home value and market changes across a given region and housing type”.
In this post I will show how to create animated graphs that illustrate the increase in buildings in Allegheny County.
One caveat about the data: it only includes parcels that were sold at some point.
In this post I will be modeling house (land parcel) sales in Pittsburgh. The data is from the WPRDC’s Parcels n’at dashboard.
The goal is to use linear modeling to predict the sale price of a house using features of the house and the property.
