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()

The paper includes *nearly all papers* published in six top psychology #journals over last 2 decades.

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.

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.
