Here is post Part 3 for the tidyAML shiny app. I have added funcitonality for selecting a parsnip function. When I say parsnip function what I mean is something like linear_reg()

Interesting new study estimating the #replicability of published research in #psychology over the past 20 years.
The paper includes *nearly all papers* published in six top psychology #journals over last 2 decades.
https://www.pnas.org/doi/10.1073/pnas.2208863120
The researchers used a #MachineLearning model (#RandomForest & logistic regression ensemble) to estimate the replication likelihood of over 14,000 #articles from 2000-2019 in six subfields of psychology.

Why stop at one decision tree when you can have a whole random forest? 🌲 🎄 🌳 😄
On Monday Dec 5, we will learn all about random forests during our R-Ladies bookclub session ▶️ Ch 11 from the book Hands on Machine Learning with R by Bradley Boehmke & Brandon Greenwell

I am quite happy with how the new version of the #rstats package spatialRF is coming along.
Many new features are already implemented, like automatic model selection, improved performance scores, and several QOL changes.
Still lots of stuff on the to-do list though: full support for discrete predictors, quantile regression, prediction to raster, improved response curves, support for sf data frames, and much more is coming.

I'm just gonna say that if r2 went from 0.18 to 0.98 then I probably did something wrong. #Rstats #RandomForest
