I'd like to see them trying this in statistical methods. "I made a new type of imputation for missing data. It works really well... but if you want to see or use it, you'll have to pay me"

We must be honest about what data we do and do not have. These are all possibilities

Are popes poisson distributed? If so I estimate there could be as many as 6 popes per km2

Both per capita and per unit area-- though I believe the standard per area illustration is that it has 2 popes per square kilometre.

What is the confidence interval on that rate please?

Do you ever come across research studies that develop or somehow validate a survey questionnaire, but don't include the actual questions? What's that about?

If two people make a yes/no decision (eg. should a student pass their viva), they'll sometimes agree even if their decisions are random. If the event is rare or very common, they'll usually agree. Cohen's kappa accounts for random agreement. 0 = random; +1/-1 = complete agreement.

These are practically oriented positions with the most important duties being supporting delivery of the trial; though after data collection is complete there will be plenty of opportunities to produce research outputs if you're interested.

Are you like me - do you love changing the fonts on your #rstats plots, but tire of fiddling around with extrafonts? Just load "ragg" and use the agg device - you can set the font in par (eg. `par(family = 'Verdana')` and you have direct access to system fonts! Thank me later.

Yes 100%!!! If it's not worth writing, it's not worth reading. And your brain tends to switch off before you realise it's AI. The output is optimised to prevent thought

A quote from "Consider Phlebas" by Iain M. Banks: "Still, the underlying point held; experience as well as common sense indicated that the most reliable method of avoiding self-extinction was not to equip oneself with the means to accomplish it in the first place."

Or worse, you find that water is dry, and then have to conclude that despite your findings, water is actually wet.

Moderately useful but only within certain paradigm. It would be more useful if you provided conversions between paradigms such as Fahrenheit to centimetres

The hype around LLMs seems to be "yes the outputs aren't good and the costs and harms outweigh the benefits, but imagine if this or a different technology was actually useful"
