Lembrando que 2027 é ano de Copa do Mundo de novo. E aqui no Brasil. Bora torcer pra mulheres incríveis - mulheres estas que não ganham milhões pra perder pênalti decisivo e que não são ex-jogadoras em atividade.

I am teaching an introduction to mathematical statistics and yesterday I introduced Bayesian inference. In one of the examples I elicited a prior distribution to the probability of Neymar be announced as a member of the Brazilian squad for the 2026 FIFA World cup.

Even for a Bayesian in an ML/AI new data science world, I find quite pleasure to prove in classroom that an MLE, under smooth conditions, is consistent and asymptotically Gaussian.

I still prefer studying a subjective, specially new subjects, using printed version books. Unfortunatelly it is quite expensive buying them from Brazil. And the most cutting edge is a subject the harder it is to find a book on that subjective in a library here. This is science inequality.

I remember last year results, some news were making fun of the android performance (the fasted one was 2h 40'). I was impressed since my aim in a half-marathon is 2hs and some androids did finish a half-marathon. Then just one year later, an android beat the human record (56') by 6 minutes! Wow!

Lightning, a running robot developed by Chinese smartphone maker Honor, finished a 21-kilometer (13 mile) run in Beijing in a stunning 50 minutes and 26 seconds, beating the human world record by more than six minutes. https://cnn.it/4mLRxQ8

It is unsafe for other Scientific meetings too. My favorite meeting is the @isba-bayesian.bsky.social, this year will be in Japan (unfortunately I won't go for personal reasons) and the next one in 28 will be in the US which I won't go either because I am not keen to pass through the visa process.

Sadly, the Global North, especially the United States, is increasingly unsafe for global health meetings www.thelancet.com/journals/lan...

"If Brazilians submitted a shoe to the Oscar, everyone would vote for it, says the Sirât's director" Really? How many awards for best international feature film has Brazil won? Well, just one in six nominations... I hope we get a second one.

Here in Brazil all graduate programs are evaluated by a government agency called CAPES, and the programs get grades up to 7 every 4 years. For reference, PhD programs usually start with 4 points. Programs with a 7 are usually internationally recognized by peers.

2026 resolutions: - starting running again (I had a knee injury just before the pandemic, then I stopped doing sports running and taekwondo) - camping / hiking (alone and/or with family). There are some great places near Rio, like the Parnaso - work less (I was this close to a burnout this year)

I have recently realised that I am not an intellectual person, some may call me a scientist which I am not sure if it is right. I am Brazilian civil servant (public health researcher) and a part time lecturer devoted to (Bayesian) stats mostly applied to infectious disease epidemiology.

SARI (Severe acute respiratory illness) cases with influenza detection in Brazil. We had a clear outbreak associated with H1N1 and some states had a second outbreak associated with H3N2. This second "wave" different from the first one is completely out of season.

Yesterday, I gave a talk on the E-vigilancia ("e-surveilance") conference at the FGV (Getúlio Vargas Foundation). My talk was about how Google trends data could improve nowcasts and short term forecasts of dengue cases in Brazil. Marcelo (Fiocruz) and Flavio (FGV) were in the same session.
