Dear Hélio, dear Gretl listers, greetings from Paris !
First, let me thank you for your nice reply on this fascinating and important
Second, a colleague is far more radical than me, and even you Hélio. He thinks
that algorithms will win, that they are interpretable and that will be few
people needed to manage them in the future. He adds to this an important
caveat: using the good set of algorithms on the good data. This is somewhat
our point of view and sound advice at the least !
Third, surely the interpretation of algorithms results will be a fascinating
new branch of data science at the intersection of computer science, statistics
Fourth, it seems that we are actors and witnesses of an interesting time where
our discipline is engaged in a new revolution.
Fifth, I am confident that mathematical statistics and econometrics will be
there in a century and beyond.
Concerning covir-19, it seem that the recent results are an accomplishement of
algorithms efficiency based on sound theory and practice.
All the best and nice week-end all.
Excellent reply from Franck Nadaud.
Me, as an outsider of this discussion (I have a degree in Operations
Research, but I work as Software Tester), I have a neutral position, or
more like a grey color in the white vs black discussion (pick one color for
Statistics ;) ). I would say the Econometricians would be more on the grey
side but with a bias to the Statistics color :).
We can see the advantages of Data Science, in processing big samples of
data and extracting patterns that a human would not be able to see (or too
live long enough to find them). (I am mostly thinking on DNA,
I am not advocating for either side, there are advantages in all these
(three sciences), it is a matter of selecting the adequate tool to solve
the problem at hand.
Currently, there is this feeling, that everyone can be a Data scientist, by
just applying a bunch of algorithms and draw conclusions from them. I think
that a good background in Statistics is essential to be a Data scientist
(as it is for an Econometrician).
When I think about this Computer Science vs Mathematical reasoning, I
always think about the Four Color Theorem
was possible to
proof with a computer executing, a mathematical model.
These days we need to stop COVIR-9 spreading in the world, hope scientists
with whatever science, tools, or techniques, they find good solutions (and
political powers listen to them).
Thank you all, for keeping doing science (and teaching)!
