This is the website for participants in the summer school Statistics for Point Patterns in Space and Beyond given by Jesper Møller, Rasmus Waagepetersen, Jakob Gulddahl Rasmussen, Christophe Biscio and Ege Rubak as part of the 1st International Summer School for PhD Students and Other Young Researchers in Aalborg, August 22-26 2022.
Location: Aalborg University, Fredrik Bajers Vej 7A room 4-108, DK-9200 Aalborg Ø
To receive a course diploma (4 ECTS) the participants will be evaluated by successful participation during the lectures, including the solution of exercises. For the final assessment, a satisfactory solution of selected exercises (henceforth called hand-in exercises) are required with deadline September 11, 2022. The hand-in exercises and to whom they should be send are listed as part of the description of each day of the workshop below. Please write your name clearly on the handin exactly as it appears on PhD Moodle, so we can easily cross reference with the participant list.
You will need a working install of R (and RStudio) with the package spatstat to participate, so please go through these steps:
If you don’t have R (mandatory) and Rstudio (optional, but highly recommended) installed please do so as described here (note as described you need to choose a non-standard install option for R during install on Windows to be sure to avoid problems)
Watch this video about using RStudio (feel free to only skim it if you are already RStudio user or consciously choose another interface to R): https://youtu.be/mAtAHwiP204
When you have R installed on your own computer, please install spatstat
(http://cran.r-project.org/package=spatstat) and all its dependencies by running this R command in the R console:
install.packages("spatstat", dependencies = TRUE)
These days are divided into a morning and afternoon session for a total of four sessions.
Each session consists of:
Topic | Lab notes | Lab exercises | Lab solutions | Hand-in exercise |
Intro and moments | Notes 1 | Lab 1 | Lab solutions 1 | Exerc. 1 in Intro sec. of slides |
Poisson and envelopes | Notes 2 | Lab 2 | Lab solutions 2 | Exerc. 2 in Poisson sec. of slides |
Cox/cluster and estimating eqns. | Notes 3 | Lab 3 | Lab solutions 3 | Exerc. 1 in Cox/cluster sec. of slides or comp. exerc. html,pdf,Rmd |
Determinantal and Markov models | Notes 4 | Lab 4 | Lab solutions 4 | Computer exercise html,pdf,Rmd |
Additional slides about determinantal point processes for session 4.
Possible hand-in exercises are listed in the table above. You need to hand in a total of three exercises for this part of the workshop. There has to be at least one theoretical exercise and one computer exercise in your hand in. Solutions for the theoretical exercises should be send to Rasmus ([email protected]) while the solution to the computer exercises should be send to Ege ([email protected]).

Topological data analysis (TDA) is a new field that aims to use tools from topology to draw information on the “shape” of data. It has in the past years been successfully used in various fields, including in spatial statistics.
However, the mathematical background and theory in TDA are often unfamiliar for most statisticians.
The aim of this session is to give you an informal introduction to TDA, with a clear understanding of its main concepts and mathematical objects.
This will be illustrated with applications in spatial statistics to assess the goodness-of-fit of a point process.
The session will be accompanied by tutorials and exercices with the R package TDA.
Please find below the slides and codes reviewed during the course. Please do not hesitate to send me an email if you have any questions.
