Everytime someone parrots the deeply flawed line that goes something like "experiments tend to have strong internal validity but weak external validity. Observational studies have strong external validity but weak internal validity," some deity drowns a puppy.

TBC, if you are using data to make a claim you are making a statistical inference. The fact that you haven’t calculated anything formally, just makes it more likely it’s a bad one.

#statstab #172 Binary Choice vs Ratings Scales Thoughts: 🔥take: "This paper argues for the adoption of binary choice over ratings scales, [as] the majority of human decision making [is] ‘system 1’" What do people think? #surveys #binary #likert journals.sagepub.com/doi/10.2501/IJ…

oh, low E-BFMI warning ⚠, why do you persist? just let me sleep... #stan #brms #modelwoes

Trying to run a conditional thresholds model in #brms with "rating | thres(gr = interaction(Time, Exp)) ~ 1 + (1|ID)" but I get "Number of thresholds is smaller than required by the response" Does anyone know what this mean? Solomon Kurz (was following: discourse.mc-stan.org/t/plotting-pp-…)

#statstab #173 Comparison of binary, ordinal and metric answer formats Thoughts: "[same] interpretations & reliability; differ in speed [...] equally simple, pleasant, and useful" I rate this result 3/5. #binary #likert #ordinal #metric #ratings #survey core.ac.uk/download/pdf/3…

#statstab #174 The Principle of Predictive Irrelevance Thoughts: "when two competing models predict a data set equally well, that data set cannot be used to discriminate the models and the data set is evidentially irrelevant" #modelcomparison #inference bayesianspectacles.org/the-principle-…

#statstab #175 Colour palettes for data visualisation Thoughts: Ending the week with some plot colour ideas - good #dataviz is just as important as good #inference! I like Sanzo Wada 006 and 232. #ggplot #rstats #plots #rpubs rpubs.com/mathetal/colors

We look forward to receiving you in Bucharest! 📷

#statstab #176 Pairwise test after a (omnibus) χ2 test of equality of proportions w/ R Thoughts: I've often had this complaint with many packages where all they offer is the overall dif, not per two cells. #chi2 #posthoc #r #rstats stats.stackexchange.com/questions/1119…

observational research is hard. it's easy to be misled. cool blog post.
