I hope I can reduce my pace, and start working on fewer and slower projects.

I wish I could talk to myself before the pandemic. "You don't need to work that much, seriously it won't make any difference..."

Each project alone is quite interesting, the problem is the large number of them that I got involved due to my profound difficulty of saying NO...

Today, I spent almost the whole day jumping from one online meeting to another, I even had lunch in front of my PC while attending another meeting.

And I forgot to add in the thread the dashboard we made to show the results of the paper:

dcpcamara-picinini-freitas-et-al-2025.share.connect.posit.cloud
A statistical model for forecasting probabilistic epidemic bands for dengue cases in Brazil

This way I don't forget mentioning anyone. :-) Thanks everyone.

Here one can see how heterogeneous is the relationship between the observed dengue cases and the model predictions in country by health regions in the two seasons (2022-2023 and 2023-2024).

We suggest the use of posterior predictive quantiles to define epidemic levels.

I would suggest this one too.

I would suggest Andrew Gelman's books

In particular, Bayesian Data Analysis and Data Analysis Using Regression and Multilevel/Hierarchical Models.

Another curiosity, in 2001 as an undergrad stats student I attended the same (joint) conference, the 46th RBRAS and the 9th SEAGRO, in Piracicaba (SP). There I gave my very first oral presentation talking about the partition product model applied on a variance changing points problem.

The conference is the 69th Annual Meeting of the Brazilian Region of the International Society of Biometrics (RBras) and the 21st Symposium on Statistics Applied to Agricultural Experimentation (SEAGRO).

This one is quite similar a species that I love and sometimes I can spot here in Rio.

I know there is plenty of time, and once one gets the visa it opens doors to other events etc... But it doesn't change the fact that to get a visa here is quite annoying, near humiliating and I am not keen to do it again (my old visa has expired)
