GeoStatBR

Geospatial analysis module for Jamovi

---

Overview

GeoStatBR is a jamovi module that executes spatial data visualization and spatial autocorrelation analysis. The module focuses on Brazilian geography, providing built-in shapefiles for all 27 states and all States municipalities.

---

Features

• Choropleth Map: Visualize any numeric variable as a color-shaded map of Brazilian states or Paraná municipalities
• Global Moran's I: Test for global spatial autocorrelation with a Moran scatter plot and permutation-based significance test
• Local Moran's I (LISA): Identify spatial clusters (High-High, Low-Low) and outliers (High-Low, Low-High) with cluster and significance maps

---

Installation

1. Open jamovi.
2. Click the Modules button in the top-right corner.
3. Select Install from file… and choose the downloaded .jmo file.
4. The GeoStatBR menu will appear in the analysis ribbon.

Analyses

Choropleth Map

Produces a thematic map that color-shades geographic regions according to a numeric variable, making spatial patterns immediately visible.

---

Global Moran's I

Tests whether values that are geographically close to each other tend to be more similar (positive autocorrelation) or more different (negative autocorrelation) than expected by chance.

---

Local Moran's I (LISA)

Decomposes the global index to identify specific locations that drive spatial autocorrelation — high-value clusters, low-value clusters, and spatial outliers.

---

Quick Start

1. Open jamovi and load your dataset (CSV or spreadsheet).
2. Click the GeoStatBR menu in the analysis ribbon.
3. Choose an analysis: Choropleth Map, Global Moran's I, or Local Moran's I (LISA).
4. Select the geographic level.
5. Select the join column, the variable in your data that identifies each region (e.g., state name or IBGE municipality code).
6. Select the variable you want to map or test.
7. The map or results appear in the output panel.
