Research synthesis is just plain hard 😡
But did you know there's a community that aims to make things easier and more accessible in R 😍
Join us at the free Evidence Synthesis & Meta-analysis in R Conference #ESMARConf2025
Abstracts due real soon: Monday April 21st!

#correlation without #causation via #ColliderBias
a spurious relationship between the dependent (Y) & independent (X) variable can occur, when each effect a 3rd variable (C, #collider), and this 3rd is included in the linear model lm(Y~X+C) 🤔

Batch downloading a bunch of papers today with R — getting a little help from #pikachu and angry oyster 🦪 from the #rstats package {switchboard} to track progress 📈

in #regression, noise is assumed independent—but none of that matters when sample sizes are low…
here the #correlation remains approximately the same at -0.065 irrespective of noise 🦖, but will range from -1 to 1 with small samples

Here’s what happens to regression 📈 when sample sizes are low…
even with a strong underlying correlation, sampling error will erode everything! 🧪 ‼️

Our campus at USF has been planting many ornamental cycads 🌿 on campus and the result has been this wonderful explosion of 10,000s coontie hairstreaks this week!! ❤️🦋 🧪

Hey new followers ❤️, here’s some realtime #dataviz you can do with #rstats & #tcltk
There is tremendous risk in repeatedly analyzing data as it comes in…
For example, in the absence of any effect, the p-values of repeated t-tests on a growing dataset will randomly walk between 1 and 0!
