DESCRIPTION: \n\n\n\n \n\nThis series of lectures will focus on statisti
cal model building\, mathematical models that describe the distributions o
f observed data in terms of a hypothesis/theory with optional parameters\,
and the use of standard statistical inference techniques on those models.
\n\n \n\nThe course is structured such that the level of difficulty gradu
ally increases over the duration of the course\, as the models are made gr
adually made more realistic and complex. At each stage ample attention is
given to practical and computational aspects of model building\, alternate
d with excursions into statistical theory.\n\n \n\nThe outline of the cou
rse is as follows\n\n \n\n Day 1 \n\n\n\n \n Model building 1 - Simple
Poisson Models \n \n \n Statistical methods 1 - Hypothesis testing\, p-va
lues\, odds ratios (demonstrated on simple Poisson counting experiments)\n
\n \n \n \n Model building 2 - Modelling distributions - template based
models or analytical models\n \n \n Statistical methods 2 - Adapting stati
stical methods to use with distributions: test statistics as ordering prin
ciple\, likelihood ratios\, contrast with Bayesian methods\, the likelih
ood principle. Practical aspects of toy MC sampling \n \n\n\n \n\nDay 2\
n\n\n \n Model building 3 - Models with parameters I - analytical parametr
ic models\, template morphing approach for histogram-based models\n \n \n
Statistical methods 3 - Inference with parameters: maximum likelihood\, co
nfidence intervals\, upper limits\, likelihood ratio and asymptotic formul
ae\n\n \n \n \n Model building 4 - Models with parameters II - simultane
ous fits\, representing external information as subsidiary measurements (
‘profile likelihood fits’)\n \n \n Statistical methods 4 - Parameters
of interest vs nuisance parameters\, dealing with nuisance parameters in i
nference methods\n \n\n\n\n \n\n\nDay 3\n\n\n \n Model building 5 - Diagn
ostics (understanding MINUIT\, fit stability and convergence) and Validati
on (understanding your fit\, overconstraining parameters\, 2-point systema
tics etc)\n \n \n Model building 6 - Advanced model building techniques: a
nalytical lagrangian morphing\, matrix element techniques \n \n\n\n
\n\n\nThe course will take place from
Wednesday Dec 12 through Friday Dec 14 with 3 lectures in the morning\, f
ollowing by a hands-on session in each afternoon to practice the technique
s discussed using ROOT-based exercises.\n\n \n\nPracticalities:\n\nThis l
ectures series is jointly offered to Nikhef PhD students and INSIGHTS PhD
students. INSIGHTS students should register for this event on this indico
page.\n\n \n\nStudents should bring a laptop for the hands-on session (fu
rther detailed information will be provided)\n\n \n\nVenue\n\nAll lecture
s will take place in room H331 at Nikhef\, Science Park 105\, Amsterdam.\n
\n \n\nComplimentary coffee\, tea and refreshments are offered during the
lectures. Lunch can be enjoyed either at the Science Park cafetaria\, in
the same building\, or at restaurants nearby (Polder\, Maslov)\n \n\nTrav
el\n\nAmsterdam Airport (Schiphol) is well (and often cheaply) connected w
ith most European airports\n\n \n\nNikhef is easily reached by train from
Schiphol airport. Travel from Schiphol Airport to Amsterdam Central stati
on by train and take from there a train that stops at Amsterdam Science Pa
rk. From there\, Nikhef is a few minutes walking. Accurate public transpor
t information is readily accessible on e.g. Google Maps. Prices for public
transport in and around Amsterdam are typically of the order of 3-5 euros
per trip. Taxis are quite expensive (count on e40 from airport to Nikhef)
and provide limited added value.\n\n \n\nAccomodation\n\nAmsterdam is a
popular tourist destination\, which is reflected in hotel prices and avail
ability. Decent hotels in the vicinity of Nikhef will cost around e100/nig
ht. The Nikhef secretariat can assist you\, if desired\, with hotel bookin
gs (we do get better rates on some hotels than those publicly advertised).
If wish to make use of this service\, please contact Ms Joan Berger (jber
ger@nikhef.nl) and indicate that you are in INSIGHTS student wishing to at
tend the statistics lectures. In any case\, aim to make hotel\nbookings (w
ith or without assistence) as soon as possible.\n \n\n \n\n \n\n \n\n
