Applied Statistics - Week 5
Monday the 14th - Friday the 18th of December 2020
The following is a description of what we will go through during this
week of the course. The chapter references and computer exercises are
considered read, understood, and solved by the beginning of the
following class, where I'll shortly go through the exercise
solution.
NOTE: Sunday the 13th (at 22:00) is the deadline for the project. At
the end of the week, we will by then essentially be done with most of
the core curriculum, and I will not introduce anything fundamentally
new on Friday, which will be dedicated to the discussion of the project
and catching up on exercises (or Problem Set). Please remember to submit
your
pendulum timing residuals.
And if you felt that making a precision measurement was hard, then please read
this short passage from "The Measure of All Things" about the making of the meter,
where one of the two main persons behind the measuring of the French meridian, Delembre,
is
struggling to get precise results.
General notes, links, and comments:
How to produce (great?) plots:
Plotting inspiration and code
Monday:
We will use two days for the last "major" theme in this course,
which is
MultiVariate Analysis (MVA), that is analysis of data
with more than one (typically many) variables. To begin with, we will
consider the relatively simple linear case, which is described by
Fisher's Discriminant, and then move on to more complex sets of
data, for which more advanced non-linear methods, such as Neural
Networks (NN) and Boosted Decision Trees (BDT) are more useful.
Reading:
NOTE: You should by now have read curriculum (roughly Barlow chapters 1-8).
Lecture(s):
Bayes Theorem
MultiVariate Analysis - Part I

Recording of Lecture video,
Lecture audio, and
Lecture chat.
Computer Exercise(s):
2par_discriminant.ipynb
fisher_discriminant.ipynb and
data.
Tuesday:
The day will focus on calibration, which is a subtle subject,
yet fairly straight forward, once you get the hang of the idea. The
associated exercise is inspired by typical data analysis work.
Reading:
No reading - logic and reason suffices.
Lecture(s):
Calibration

Friday:
On Friday the 18th of December (last day of course in 2020), I will not introduce
anything new, but simply give a short summary/overview of the course so far and a
review of the project experiments.
In the exercise session, we will simply catch up and ask all the questions you
might like to resolve before Christmas.
Reading:
You should by now have read curriculum
(roughly Barlow chapters 1-8).

Computer Exercise(s):
Catch up on previous exercises (perhaps in particular those related to the Problem Set!).
