This post is only used to record that I have listened to this seminar:

Survival Extrapolation with applications in health economics [click here to download PDF]
	Nikos Demiris (Agricultural University of Athens)
	UPF Statistics and Operational Research Seminar

However, I didn't understand anything except the exponential equation. I had thought I would understand more, since I know a little about survival analysis (What I have learned on the Chinese R conference), and a little about health economics. But on the seminar I realized that it was beyond my scope of knowledge. Anyway, there were only 4 people (before I showed up), and my dear math teacher Lugosi was there! Lugosi, YOU ARE AMAZING!

Since I didn't actually benefit something from the lecture, it is impossible to leave any comments here. Therefore, I'd like to talk about something about economics. Well, I always wonder whether I can always pick up someone to go to the seminar together with me. It is not important whether you are able to understand what they are saying, but the atmosphere can help you adapt to the way that economists think in. Without doubt, there are only few people who prefer seminars to those time-consuming problem sets. Thus, the final conclusion is that I should go anywhere alone.

I have no right to force anyone to do anything. It's their own choices - and I choose seminars. Maybe it is a bad habit, since it is probable that I cannot get anything useful from a seminar. But I love the way they talk and communicate in the seminar, and I love the different stories that the researchers show in their presentations.

As what I wrote on the front page of this website (www.cloudlychen.net) -  "Love life, love economics", I always regard economics as a living object. Economics is from the real world, not the mathematical equations. Although we need math that complicated enough to describe the economic world specifically, the economics is, and will always be focusing on the real world. Apart from those who are engaging themselves into developing new mathematical methods for economics (e.g. theoretical  econometricians and mathematical economists), who want to explore the world of economics should pay attention to the real life of economics.

Fine, anyway I should judge anything. At least, for me, economics is always alive around everybody and everyday.
