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...

There is no better use for this gif than the video and linked part below.

You can use geometry to convert effect sizes like Hedges’ g and response ratios? ‼️ 🧪 #math #statistics #synthesis #ecology Read more here: onlinelibrary.wiley.com/doi/abs/10.1...

It’s easy to miss seasonal changes in Tampa — but our favorite marker is when the common snapping turtles 🐢 come out to eat our orange Queen palm 🌴 seeds — this event also signals the return of our yard alligator! 🐊❤️ 🧪

@lajeunesselab.bsky.social has written the paper that meta-analysts were waiting for, and I can't recommend it more: Converting and Constructing Effect Sizes With the Response Ratio doi.org/10.1111/ele.... Go check it out (and use it!)

Really cool. PIVOT!!

Drama for millennial scientists is all you needed today and you didn't know it.

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):

TIL: random effects meta-analysis in Excel, thanks to @lajeunesselab.bsky.social 's perfect YouTubeTorial (Yes I can program & use stats software, but until I crunch the numbers in a spreadsheet, I don't really understand it. Now I know Kung Fu) ps: it's as easy as ANOVA youtu.be/i66Lf2a_Pa8?...

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

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 📈 #happyFriday!

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

I use #RStats for systematic reviews. RISmed package to extract meta-data and abstract text for each article from PubMed. metagear package to screen articles & save the decision

Although horrifying, null study outcomes and null effects are ok you goblins happy Halloween 🎃 #rstats

Oh shit — this is for real now #rstats

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!

Taking a stab at a starter pack of Evolutionary Biologists — this was trickier than expected both because of the interface setup and because of the 150-person limit go.bsky.app/TUNHbNu

I tried to build a starter pack for researchers in ecology sensu lato. Who am I missing? go.bsky.app/2MdGeqi I can add more people and spread it around.

I made an #RSats starter pack. Includes a touch of Linux, Python, and dataviz but mostly R. go.bsky.app/Ki7PjpS

As I have a🍺 & wait for #Milton to take my home… I’m reminded of simpler times, when I decided to post +25 hours of #YouTube videos of me doing a complete meta-analysis from scratch on a topic I barely knew anything about Do what you love friends! youtu.be/rM4MQA5hU6c?...
