Statistics Workshop - Guidelines for Reporting Methods & Results
by Information about statistics events at AGRO 19 Nov '25

19 Nov '25

Hello Everyone! On November 19th we'll be hosting a themed workshop in which we'll present and discuss good practices for reporting statistical methods and results. The workshop will be hosted in Flakkebjerg, but it will be possible to participate in AU Viborg or remotely on Teams. The presentation will last about an hour, followed by questions and discussion. We hope to see you all there, and please share this invitation with others who you think may also be interested in participating. Regards, Simon ________________________________________________________________________________ Microsoft Teams Need help?<https://aka.ms/JoinTeamsMeeting?omkt=en-US> Join the meeting now<https://teams.microsoft.com/l/meetup-join/19%3ameeting_ZTg4ZDFhOGMtN2NlMy00…> Meeting ID: 392 449 993 145 78 Passcode: YR2cG6gz ________________________________ Dial in by phone +45 32 73 55 36,,976971583#<tel:+4532735536,,976971583#> Denmark, All locations Find a local number<https://dialin.teams.microsoft.com/8ad9a387-92fd-4e73-9dd7-bfa4e94dd900?id=…> Phone conference ID: 976 971 583# Join on a video conferencing device Tenant key: aarhusuni(a)m.webex.com Video ID: 122 051 600 2 More info<https://www.webex.com/msteams?confid=1220516002&tenantkey=aarhusuni&domain=…> For organizers: Meeting options<https://teams.microsoft.com/meetingOptions/?organizerId=d1717b86-e3e2-48d0-…> | Reset dial-in PIN<https://dialin.teams.microsoft.com/usp/pstnconferencing> ________________________________________________________________________________

FW: Statistics Phd courses offered by ANIVET in 2026
by Statistics AGRO 13 Nov '25

13 Nov '25

Please see below PhD courses offered by ANIVET that may be of interest to PhDs in AGRO. From: Gavin L. Simpson <gavin(a)anivet.au.dk> Sent: 13 November 2025 12:42 To: Gavin L. Simpson <gavin(a)anivet.au.dk> Subject: Statistics Phd courses offered by ANIVET in 2026 Dear colleagues, Supervisors: please forward to PhD candidates or colleagues who might benefit from taking one or more of the courses. Further to my email in September, I can confirm the dates for the three PhD courses in applied statistics that I will be offering in 2026: 1. Applied regression modelling with R, 14-16th April 2026 https://event.au.dk/events/applied-regression-modelling-with-r 1. Multivariate data analysis with R, 28-30th April 2026 https://event.au.dk/events/multivariate-data-analysis-with-r 1. Generalized additive modelling with R, 9-11 June 2026 https://event.au.dk/events/generalized-additive-modelling-with-r Each of the courses will take place at the AU Viborg campus and are in person events. There is a small registration fee for each course of DKK400 to cover morning and afternoon refreshments. The links above for each course are registration links; if you wish to take any of the courses, please register to secure your spot. The courses will be advertised on the Tech Graduate School PhD course list soon. Brief details on the courses are given below. The Applied regression modelling course is a slight redesign of the “Mixed Modelling” course I ran in January, with the name change reflecting that the course covers a broader set of models than just mixed effects ones. It will cover generalised linear models and generalised linear mixed effects models, and include fitting, diagnosing problems with, and interrogating those models to extract parameters and values of interest. This is a general practical modelling course in R, so will not expect much prior knowledge. The focus will be on the lme4 and glmmTMB packages and using the marginaleffects package to extract and test values of scientific interest. Details on the previous version of the course are available here: https://phd.tech.au.dk/for-phd-students/courses/scientific-courses/kurser-2… The Multivariate data analysis course will be like the one I have taught previously but will cover microbiome / sequencing data more in the examples and methods than in previous years. Details on the previous version of the course are available here: https://phd.tech.au.dk/for-phd-students/courses/scientific-courses/kurser-2… The Generalized Additive Models (GAM) course will be very similar to the one I taught in 2024 but updated with some more Animal Science / Vet examples. This course is for anyone interested in modelling non-linear effects of variables on responses. Details on the previous version of the course are available here: https://phd.tech.au.dk/for-phd-students/courses/scientific-courses/kurser-2… If you have any questions about the content of these courses, please direct them to me. Best wishes Gavin -- Gavin Simpson — Assistant Professor Department of Animal & Veterinary Science — Aarhus University Building 8856 (G20); Room 3064, Blichers Allé 20, 8830 Tjele, Denmark 📧 gavin(a)anivet.au.dk<mailto:gavin@anivet.au.dk> 📞 +45 22 27 04 33<tel:+4522270433> 💻 https://pure.au.dk/portal/en/persons/gavin%40anivet.au.dk 💻 https://fromthebottomoftheheap.net<https://fromthebottomoftheheap.net/>

Stats workshop follow-up: Piecewise regression resources
by Information about statistics events at AGRO 12 Nov '25

12 Nov '25

Hi all, Today in the later half of the statistics workshop, we discussed piecewise regression as a possible solution to a question brought up to discussion. To provide some more help and resources for how to run a piecewise regression in practice, see below. What is piecewise regression? For some context for those of you who do not know what piecewise regression is: it has many names - piecewise regression, segmented analysis, changepoint analysis, breakpoint analysis, etc. Essentially, it is a regression analysis where the slope changes at certain points (=breakpoints) of the x-axis. A research question can be focused on estimating the slopes at different segments, discovering whether breakpoint(s) exist, or both. See the figure below for a (made-up) example of how a slope can change in segments determined by 2 breakpoints. Analysis can be segmented, when the x-axis has continuity and the segments connect to one another (like in the figure), or stegmented, where the segments do not connect, but rather there is a jump to a different starting point for each segment. [cid:image003.png@01DC540A.E6E49B20] Resources You can find a template/tutorial for how to run piecewise regression in R, from GitHub following the link below. Some of you may have received different versions of this code previously, and it has evolved over time, and may keep evolving in the future. You can copy or download the script to run it in your own computer. https://github.com/MaaritIMaenpaa/Stats101/blob/main/example_code/Piecewise… For more information, take a look at the tutorials for specific packages below. Which R package you need will depend on your focus and your data. Package segmented: An overview of how to do piecewise regression: https://www.youtube.com/watch?v=NRaFJG1jWoQ Minimum words, but nice code to show what a segmented model can do: https://rpubs.com/MarkusLoew/12164 A tutorial for strucchange (alternative package) can be found here: https://kevin-kotze.gitlab.io/tsm/ts-2-tut/ A tutorial for yet another package, mcp: https://lindeloev.github.io/mcp/ Good luck for your analyses, and happy coding! 😊 Best regards, Maarit Maarit Mäenpää Statistician Dept. of Agroecology Aarhus University Blichers Allé 20, Postboks 50 DK-8830 Tjele Web: agro.au.dk Phone: 51 335 104 E-mail: m.maenpaa(a)agro.au.dk<mailto:m.maenpaa@agro.au.dk> AGRO employee?

Dear all, Struggling to make your graphs look great in your papers or thesis? You're not alone! Next week, on Wednesday, November 12th, we’re excited to welcome @Fiona Hay<mailto:fiona.hay@agro.au.dk> as a guest presenter in the Statistics Workshop. Fiona will introduce Origin, a user-friendly data analysis and graphing tool that can be a good alternative to R, especially for graduate students whose work isn’t heavily focused on statistics. Learn more about Origin here<https://www.originlab.com/origin> Presentation time: 🕒 13:30–14:10 After Fiona’s talk, we’ll continue with our usual open session for any statistical questions or support you might need. Looking forward to seeing many of you there!
