Learn how to simulate correlated data from different probability distributions using the Gaussian copula & base #RStats. The guide generates correlated operative performance variables, including "# air knots", "passing point count", & "preop practice time" thomasward.com/simulating-cor…

This, and the package it builds upon, ggdist mjskay.github.io/ggdist/ are so useful for visualizing data distributions.

Video recorders, especially those in the OR, record multiple small videos instead of one large one. Quickly combine them, trim excess video from the ends, and more, with my Python script "video_processor": README here github.com/tmward/tmw-mis… & code here github.com/tmward/tmw-mis…

Thank you for the invitation to speak! I had a great time. If anyone missed my talk on AI Technologies in Endoscopy, slides are available here thomasward.com/talks/ircad-fl… & contact me with any questions you may have.

This is a well-done and thoughtful intro to R, from data shaping/cleaning/visualizing (similar to R4DS) to performing different statistical analyses. I wish this existed when I started to learn and use R! Peter van Galen

Annotating surgical video can be challenging & Thomas Ward Dan Fer MD MGH SAIIL outlined these challenges & some proposed ways to overcome them in our newest paper in Computer-Assisted Surgery tandfonline.com/doi/full/10.10… #computervision #AI #surgery

Over 18 months & a pandemic ago, SAGES is in Long Beach in 2025! convened experts in #surgery & #CS to tackle inconsistent annotation of video for #AI w/ hopes of improving reporting, transparency, and inter-institutional research Consensus framework on annotation now available in Surgical Endoscopy!
