I made a Shiny app to showcase the differences between using a linear fit, a categorical fit and a (restricted cubic) spline fit under various data generating mechanisms.
The app is available at: apps.biostat.au.dk/stefan/splin...
Feel free to use it in your teaching #rstats #datascience #statssky

Happy to announce ✨quarto-revealjs-editable✨
This fully supersedes the imagemover extension, as I back then didn't realize the potential. You can now also move, resize, change font size and alignment for text in your slides

Vibe-estimanding is my new favorite expression! A concise description of a widespread phenomenon in health science research.
Yeah. Confusing. I do enjoy having conversations when people use language like this to know what they actually mean. Usually what they’re actually doing though is vibe-estimanding

Now on CRAN, ggdiagram is a #ggplot2 extension that draws diagrams programmatically in #Rstats. Allows for precise control in how objects, labels, and equations are placed in relation to each other.

Consider the following DAG where both exposure and frailty have positive effects on pregnancy (P) and healthy child (Y). Say, I'm interested in the effect of the exposure on having healthy children in my population. #stats #causalsky #episky #statsky #causalinference

I've made my first R package {ciwidth}. It's nothing big, but it lets you calculate the sample size needed for obtaining a confidence interval for a mean or mean difference with a certain width with a given probability. Take a look here: github.com/snhansen/ciw... #rstats #statssky

I did update the figure a bit and added labels, but it probably works better as sequential slides in a presentation. If you want the code and the pptx just drop me a dm and I’ll send it all your way.

With respect, this suggests quite a serious misunderstanding about why we randomise. We do this to ensure imbalances are random. Our analyses treat them as such, and ensure valid inference. The problem here is with the idea that point estimates are useful, rather than with randomisation.
