For model calibration (esp via logistic regression), does anyone know of a statistical investigation of the properties of the resulting calibrated predictions?
IOW, if we use predictions from one model as inputs to another model, do we know the probability distribution of the final predictions?
It would enable the relatively easy creation of serious games and interactive exercises to learn R or statistics (or with the {rock} package, qualitative research); combining R with a simple game/adventure engine.
I just published a very basic introduction to using Boston's #Bluebikes bikeshare system data in #RStats. IMHO this is a great, underutilized dataset and is especially well-suited for student projects!
I've always wanted to try to get axis text directly on my plots like I've seen in the New York Times and other places. Finally figured it out with the help of the {ggh4x} package. Code here: https://rfor.us/axistext#rstats
We're very excited to be hosting three reading groups at eCOTS over the next few weeks, and we'll be introducing them this week!
The first reading group is on the topic of "What do students learn from simulations in statistics?" and is facilitated by Andrew Pua, and will be happening May 21 10pm BST / 5pm EDT / May 22 5am Philippine Standard Time
The End To End Data Science With R is a new book by Rene Essomba. The book, as the name implies, focuses on the core data science applications using R ❤️. This book covers the following topics:
✅ Exploratory data analysis
✅ Data visualization
✅ Supervised learning
✅ Unsupervised learning
✅ Time series
✅ Natural language processing
✅ Image classification
Check out another fireside chat hosted by Audrey Yeo, featuring Heather Turner and Abhishek Ulayil. This week's chat is on building foundations for R’s future as an accessible and diverse collaboration.
Heather is an R Foundation member with a strong track record promoting diversity in contributions to R, while Abhishek has recently converted the R Journal content to more accessible web content, and keynote speaker at useR! 2024.
A new release of #rstats broom is on CRAN! v1.0.6 includes several changes to well-used tidiers from the package, e.g. for lm(), gam(), and survfit() output.
Next Tuesday I'll be part of a Fireside Chat alongside #useR2024 keynote Abhishek Ulayil on the topic of "Building foundations for R’s future as an accessible and diverse collaboration".
Thank you continuous backups! I was working in RStudio and the git pane was showing "./" as being staged and I was unable to unstage it. It displayed a small amount of code from one R function, so I just reverted it after backing up that file... which reverted ALL the files in the repo to their last state (with days worth of work being gone) 😬 😬 😬
Thankfully I was able to pull versions of the files from an hour prior from backblaze, with minimal work lost
Rendering the moon's craters with displacement mapping in R with rayrender! If you noticed they appear unphysically large, it's because I'm using a information communication technique long employed by cereal boxes: the data have been enlarged to show texture 😉
Learn how to handle rows in R containing specific strings using base R's grep() and dplyr's filter() with str_detect(). Select or drop rows efficiently and enhance your data manipulation skills. Give it a try with your datasets for better data cleaning and organization.
