Overview of this book

Data scientists, when presented with a myriad of data, can often lose sight of how to present geospatial analyses in a meaningful way so that it makes sense to everyone. Using Python to visualize data helps stakeholders in less technical roles to understand the problem and seek solutions. The goal of this book is to help data scientists and GIS professionals learn and implement geospatial data science workflows using Python. Throughout this book, you’ll uncover numerous geospatial Python libraries with which you can develop end-to-end spatial data science workflows. You’ll learn how to read, process, and manipulate spatial data effectively. With data in hand, you’ll move on to crafting spatial data visualizations to better understand and tell the story of your data through static and dynamic mapping applications. As you progress through the book, you’ll find yourself developing geospatial AI and ML models focused on clustering, regression, and optimization. The use cases can be leveraged as building blocks for more advanced work in a variety of industries. By the end of the book, you’ll be able to tackle random data, find meaningful correlations, and make geospatial data models.

Summary

In this chapter, we walked you through the construction of spatial regression models to better understand the drivers of nightly Airbnb prices in NYC. We started the chapter off with a refresher on OLS regression models. Using this model, we looked at the distribution of the model’s residuals to better understand some latent spatial structures that needed to be accounted for.

In the second section, you learned how to incorporate spatially engineered proximity features into the model, which dramatically improved the model’s performance. We then introduced you to spatial fixed effects and how to use the spreg library's OLS_Regimes function to build a spatial fixed effects model, which further improved performance. Within this section, we also introduced the Chow test to ensure that the neighborhoods yielded statistically different results.

In the second section, you learned about GWR and MGWR, which are models that fit local regressions for each observation...
