Statistics Spatial&Spatio-temp. Data  

The premise of the course is motivated by the recent advancements in geoinformation data acquisition and storage and their intended use for evidence-based planning and monitoring. The spatial references of geo-information data may be attributed to the exact locations of measurements or over a fixed set of contiguous regions or lattices. This course seeks to handle the three main classes of spatial data/processes: geostatistical data/spatially continuous process, lattice data/discrete process, and point pattern data/point process. Such data appear common in diverse application fields like environmental science, agriculture, natural resources, environmental epidemiology, and so on. The aim is to present methods that can be used to explore and model such data. Naturally, data vary in space and in time; hence data close to each other (either in space or time) are more similar than those farther. Geostatistical modeling based on the semivariance and/or covariances and interpolation (kriging) in space and time will therefore be introduced. The methods will be extended and applied to data aggregated over contagious regions. The uncertainty is quantified, and attention will be given to making maps showing the probabilities that thresholds are exceeded. Attention is also given to optimal sampling and monitoring. Further, data that arise out of the occurrences of events; thus point pattern data will be considered. The significance of exploring the first and second-order properties of point patterns in diverse application domains like environmental and disaster (like earthquakes) modeling will be explained and applied. The last focus will be on lattice data; in principle, this kind of data consists of observed values over a set of fixed contiguous regions. This kind of data is rather easy to acquire and is mostly applied in health studies where data aggregation is a standard form of protecting locational privacy.

The delivery of this course is partitioned into two: teaching, which embodies lectures, feedback, and Q&A sessions. There are feedback sessions 15 minutes before the start of every days’ lecture except day 1. These involve presentations delivered by students (in groups) followed by “questions” from their colleagues. The objective is to ensure students have control over the subject and also develop/encourage the skills to work in multinational groups. The groups are predefined (by myself) to avoid biases to ensure internationalization. The Q&A sessions are ensured after each lecture. Here, the students are encouraged to ask questions or share their experiences pertaining to the topic. Tutorial sessions are critical to this course as they offer the opportunity to practice the theory in the class. The tutorials for the first three topics are designed to be supervised; the remaining are unsupervised. The reason being that after the three supervised tutorials students would have gained enough skills and experience to advance student-centered learning. Critical to the design of this course is the mapping exercise and the mini-projects which take 10 and 40 percent of the assessment, respectively. The mapping exercise is to ensure that students can take basic instructions per the materials developed. The mini-project is designed to primarily ensure that students “gain experience and understanding to design and setup a space-time data modelling problem, identity measurable objectives, the modelling ideas in the R statistical software”.
