11-15 March 2024
To foster international participation, this course will be held online
The course will introduce spatial statistical methods with emphasis on spatial sampling, point pattern analysis, geostatistical analysis, mixed linear and non-linear regression models, and
machine learning methods applied to spatial variables. Underlying problems such as handling very large datasets and using large scale satellite imagery will be discussed. Theory will be explained
and illustrated by practical applications that can be reproduced by the participants. Exercises will be provided to participants for developing an independent command of the materials.
This course is aimed at higher degree research students and early career researchers working with or with an interest in spatial data and applying spatial statistical methods, with emphasis on
the biology and ecology domains. Some familiarity with R, R package sf, and the tidyverse is assumed. Familiarity with basic statistics, linear regression, standard errors, confidence intervals
and prediction will be very useful.
- Understanding of the different spatial statistical data types (point patterns, geostatistical data, lattice data)
- Understanding of spatial dependence, and its role in analysing spatial data
- Hands-on experience with spatial statistical methods and software in R, and a number of R spatial packages
- Understanding of the challenges of using big spatial datasets, and ways to handle them
Daily on-line meetings, 15:00-18:00 CET; offline communication through Slack
