Tea and Grit www.helenwatsonwriting.com by @helenwatsonwriter.bsky.social is now officially published. DOI Helen Watson is my daughter!

I have been invited to write a book with the title “AI statistics/ statistics for ML”. I can only assume that this invitation has been written by AI since, obviously “maximum likelihood for statistics” is a plausible title but the converse is not.

Today’s hike was from Eight Mile Burn to Flotterstone via W& E Kip. #hiking #Pentlands #Scotland

I am a sick as a parrot #LUFC

My latest rant is on "two-way ANOVA" (ugh!) www.linkedin.com/pulse/two-wa...

“The difference between an orchestra and econometrics is that the former has variable instruments.” Sayings of Confuseus

"The predictions here are not of future events, as in the context of time-series analysis, but rather of what would have happened in the experiment if other conditions had prevailed." I'm baffled. This is from a paper of 1982. But experts inform me that causality is never considered in statistics.

A dull day today, so instead of my usual Thursday hike I had a wee stroll. I was rewarded by seeing this heron in Braidburn Valley Park. #Edinburgh
