You should be familiar with Python, GeoPandas, and Jupyter Notebooks and have a working environment.

Vector data analysis in Python with GeoPandas, statsmodels, Scikit-learn, and PySAL

Basic concepts of statistical modeling

Pandas tools for data preparation

Feature eeering methods

Linear Regression

Logistic Regression

Other supervised classification methods

Unsupervised classification methods

Non-parametric regression

Dealing with spatial autocorrelation

This knowledge can be gained through my courses "Survey of Python for GIS applications" and "Geospatial Data Science with Python: GeoPandas"

You should have some familiarity with basic statistics, especially Linear Regression.

In this course I demonstrate open source python packages for the analysis of vector-based geospatial data. I use Jupyter Notebooks as an interactive Python environment. GeoPandas is used for reading and storing geospatial data, exploratory data analysis, preparing data for use in statistical models (feature eeering, dealing with outlier and missing data, etc.), and simple plotting. Statsmodels is used for statistical inference as it provides more detail on the explanatory power of individual explanatory variables and a framework for model selection. Scikit-learn is used for machine learning applications as it includes many advanced machine learning algorithms, as well as tools for cross-validation, regularization, assessing model performance, and more.

This is a project-based course. I use real data related to biodiversity in Mexico and walk through the entire process, from both a statistical inference and machine learning perspective. I use linear regression as the basis for developing conceptual understanding of the methodology and then also discuss Poisson Regression, Logistic Regression, Decision trees, Random Forests, K-NN classification, and unsupervised classification methods such as PCA and K-means clustering.

Throughout the course, the focus is on geospatial data and special considerations for spatial data such as spatial joins, map plotting, and dealing with spatial autocorrelation.

Important concepts including model selection, maximum likelihood estimation, differences between statistical inference and machine learning and more are explained conceptually in a manner intended for geospatial professionals rather than statisticians.

Geospatial professionals who are interested in learning more about the machine learning tools for vector data in the Python geospatial stack.
