Ok! PCA before + after correction done! Or should I say Dunn? :) Big thanks to @BroadhurstDavid for communicating their work. Current work based on Dunn et al., 2011 but in forthcoming analyses, a thing or 2 are eligible for update based on Broadhurst et al., 2018 #metabolomics

It never ceases to amaze me what people can make with gganimate #rstats

#RStats — Can we scrape the online documentation of an API to automate the creation of an R wrapper 📦? Spoiler: yes. "Automate the Creation of an API Wrapper package by Scraping its Online Documentation" colinfay.me/fun-from-api-d…

@biologeek it wouldn't be the first R library that python needed to copy. i like the idea, don't know about it being a standard tho. thanks :)

is there a format that allows users to add metadata to a csv file? it seems really sensible to be able to do something like `dataframe.explain(colname)` but it is hard to find a standard for this.

@_ColinFay upvoting qs- handles any R object and comparable to fst in speed. The main difference from fst is qs doesn’t support random access, eg how fst allows reading only specific cols/rows. But read/write speeds overall close. I think they share a bunch of implementation strategies.

Retweeting because I am really excited about this. I am willing to bet that 1) thinking about the next hypothesis you will test in machine readable terms will immediately improve what you are doing, and 2) better meta-data will make science massively more efficient.

New preprint with @LisaDeBruine where we make the case for machine readable hypothesis tests psyarxiv.com/5xcda/. We give a real-life example, argue this would improve the rigour and falsifiability of hypothesis tests, as well as facilitate the re-use of key info in articles.

TIL: I learnt about the conflicted 📦 My filter function always gets masked, so my solution till today was dplyr::filter. But there is a better way! You can set your function:library preference at the top of your script! 😭🙏 e.g. conflict_prefer("filter", "dplyr") #rstats

A thread of classifiers learning a decision rule. Dashed line is optimal boundary. Animations with #gganimate by @thomasp85 and @drob. #rstats Logistic regression {stats::glm} with each class having normally distributed features. (1/n)

@thomasp85 I finally got around to looking up the linear algebra of matrix rotations for my PCA explanation.

Are there any pointers or references to trashcan or garbage clusters? i.e. where you cluster noisy data and end up with a cluster where all the outlying points that don't fit with anything else are dumped together? Writing a review and I wonder if it's been formally recognised.

@92jackzou We explain the concept of calibration in the link below. In short, calibration is about the predicted risks (probabilities) that come out of your prediction model and whether or not these risks are consistent with the proportion of events you observed twitter.com/MaartenvSmeden…

Instead of referring to myself as self-taught, I'm gonna start referring to myself as community-taught. The sites, the blogs, the books, the user groups, the confs, the forums ... all community efforts that I used to learn and advance my programming and data science knowledge.
