[Nelson Areal @nareal]

Relação entre a proporção de votos do ADN e AD. Comparação dos concelhos do território nacional (excluindo a RA da Madeira); e os votos da ADN e da Madeira Primeiro (PPD/PSD.CDS-PP). A correlação é elevada, e maior quando a ADN surge primeiro. Análise sugerida por @LConraria

"In his white paper “Would Chat GPT3 Get a Wharton MBA?” published this week, he concluded: “Chat GPT3 would have received a B to B- grade on the exam. This has important implications for business school education." https://t.co/IWwy6xDprW

ChatGPT’s current killer app isn’t search, therapy, doing math, controlling browsers, emulating a virtual machine, or any of that other cherrypicked examples that come with huge disclaimers.

@duckdb @ApacheArrow Thanks so much

[Nelson Areal @nareal]

@duckdb is nothing short of magic. However, when using with an @ApacheArrow dataset a simple count can be 40x slower. Is this to be expected?

[scott cunningham @causalinf]

Many students starting out for the first time ask "Which stats software should I use? R or Stata?" The debates have gotten stale so I hired the couple on TikTok again to come in and give their two cents.
