How to Use GeoDa's Features
Getting Started: Input, Mapping and Table Operations
- Getting Started with GeoDa (Load shape file - menu options)
- Creating Choropleth Maps (Quantile - Percentile - Box - Std Dev Maps - Selection)
- Basic Table Operations (Select - sort - query - new fields)
- Creating a Point Shape File (Input formats - import as point shape file)
- Creating Polygon Shape Files (Polygon from boundary file and grid - join data)
- Transforming Point and Polygon Shape Files (Polygons to points and text - add centroids - points to polygons)
Exploratory (Spatial) Data Analysis
- EDA Basics, Linking & Brushing (Histogram - box plot)
- Scatter Plot & Correlation Plot (Exclude observations - brush)
- Scatter Plot Matrix
- 3D Scatter Plot
- Conditional Map & Plot
- Cartogram, Parallel Coordinate Plot & Map Movie
Weights and Spatial Autocorrelation
- Contiguity-Based Spatial Weights (1st order rook/queen - higher order - weights histogram)
- Distance-Based Spatial Weights (Distance weights - KNN weights)
- Spatially Lagged Variables (Create lags - manually contruct Moran scatter plot)
- Global Spatial Autocorrelation (Moran scatter plot - significance - brush - save)
- Local Spatial Autocorrelation (LISA map - significance)
- Bivariate Global and Local Spatial Autocorrelation (Moran scatter plot - LISA)
Rates
- Basic Rate Mapping (Raw rate map - excess risk map - save rates)
- Rate Smoothing (EB smoothing - spatial rate smoothing - save rates)
- Spatial Autocorrelation Analysis for Rates (EB Moran scatter plot - EB LISA maps)
