Ecologists love response ratios for meta-analysis❤️ But… they can’t be converted into other effect sizes—making it impossible to have a unified dataset of all published effect sizes in ecology I fix this with a conversion to Hedges’ d to help unify our data! (Link to Ecology Letters paper below):

My latest blog on evidence synthesis in ecology. We often see reviews that claim to have followed PRISMA. But PRISMA is not a conduct guide but a reporting guideline. Why does this matter? Have a read and find out! «PRISMA is not the method you are looking for». drmattg.github.io/Uncertain_Ec...

Ecological meta-analyses often inherit medical assumptions. High heterogeneity, small sample sizes, etc. break those assumptions. In the first post of a new series, I show why a “significant pooled effect” can be statistically correct but practically unhelpful. drmattg.github.io/Uncertain_Ec...

#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) 🤔 #Rstats #CausalModelling #dataviz

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 #rstats #dataviz #regression #statistics

Here’s what happens to regression 📈 when sample sizes are low… even with a strong underlying correlation, sampling error will erode everything! 🧪 ‼️ #rstats simulation viz via the switchboard package for R
