This example shows how to identify spacetime clusters. In particular, we will perform space temporal analysis to identify traffic accident hotspots using the location and time of accidents in the city of Barcelona in 2018.
Spacetime hotspots are computed using an extension of the Getis Ord Gi* statistics that measures the degree to which data values are clustered together in space and time.

This example demonstrate how to use Worklfows to apply a Geographically Weighted Regression model to find relationships between a set of predictor variables and an outcome of interest.
In this case, we're going to analyze the relationship between Airbnb’s listings in Berlin and the number of bedrooms and bathrooms available at these listings.
In this example, we will use the Create Score Unsupervised component, to identify areas in Milan with a larger market potential for a wellness & beauty center mainly aimed for teenage and adult women.
This example workflow uses the Detect Space-time Anomalies component to find the most significant clusters of anomalous data.
We’ll create a workflow to improve portfolio management for real estate insurers by identifying vacant buildings in areas experiencing anomalously high rates of violent crime.
