NS banned hiking & cycling in woods over wildfire risk, but only 2.4% of 2025 fires started on trails. I analyzed 124 fires to test this ban. The burn ban? Checks out. Closing the woods? Not so much. 🧵@nsgov @HikeNovaScotia

Check my map, see the data, check my decisions/math, share your take! ➡️timdisher.github.io/nsfires/ #NovaScotia

I think the most controversial decision on this map might be whether the ongoing Susies lake fire counts as on trail since there is a trail in the area. I have it marked it as structure/property for now since my understanding is that it's not related to the hiking trails

Bracing myself for the flames but I have been wondering if @stephensenn's effect size for powering trials as the "effect you wouldn't want to miss" offers a more charitable view of the process of balancing budgets and statistical considerations in trial planning. 1/2

Like sure I'd love to be able to design a trial to detect the smallest clinically relevant effect but I have $100k and I wouldn't wan't to miss a larger effect, assuming I have a reason to believe it's possible?

Congrats @dnunan79 and team! This is an important contribution to discourse around value/validity of GRADE. Still processing but my initial takeaway is directionally promising but not as convincing as hoped jclinepi.com/article/S0895-4…

Extra interesting given from what I can tell on quick analysis of data from Table 2 using penalized GLM there's no difference between high vs not high level evidence in terms of probability of update leading to sign change in the estimate.

I assume even less likely to see a *meaningful* change in direction, or change in direction if originally significant? Makes me wonder whether summaries of decision sensitivity to uncertainty captured in the estimate itself using threshold analysis or pred intervals would suffice

Anyone happen to know how to f/u on pathology in Nova Scotia? Friend of mine waiting 4 wks for path results on sentinal node biopsy from melanoma after waiting 7 wks for initial dx + confirmation margins werent clean. Is there something we can do to get this moving? @CBCNS

Quick little qualitative analysis dashboard for #TTPD. Hoping to inoculate against lazy takes. Powered by GPT4Turbo but hoping to serve as a starting point rather than any final word 🫡 timdisher.shinyapps.io/ttpdA…

Sometimes I wonder if I’m doing enough good in the world. Today the answer is yes. Just in time for #Swiftmas Presenting #SwiftSearch a GPT-3 powered semantic search for themes in @taylorswift13 songs. Finally you can know “what TS song am I?” eversana-shiny.shinyapps.io/… #Swifties
