Archives: The course page for the 1999 lectures.

Aims: The purpose of the course is to present the basic mathematical tools needed for the statistical analysis of experimental data. The methods will be practiced by writing and running short computer programs. The course will also include several lectures on the basics of computing in High Energy Physics.

Syllabus: A general outline of the course topics.

Schedule: Mondays 10 to 12, starting 2 October for 4 weeks; after that see the timetable for all of the postgraduate lectures.

Books: The lectures will mainly follow

G. Cowan, Statistical Data Analysis, Clarendon Press, Oxford, 1998.

Lecture Notes (print out and bring to lecture):

Problem sheets:

Some material for the tutorials and supplementary notes:

• Some information on PAW.
• A simple FORTRAN program, make_data.f, a file for compiling and linking it, make_data.lnk, and a file for looking at the output with PAW, plot_data.kumac.
• Another simple FORTRAN program to demonstrate HBOOK routines, test_hbook.f. It calls a subroutine get_another_x_value.f, and the whole thing can be compiled and linked with the script test_hbook.lnk.
• A note on how to use gmake (ps, pdf); the example files Makefile, hello.cc, goodbye.cc, and goodbye.h.
• A FORTRAN program to demonstrate use of the random number generator RANMAR, test_ranmar.f, and a script to compile and link, test_ranmar.lnk.
• Routines for FORTRAN-callable fitting with MINUIT: fit_galileo.f, fcn_galileo.f, fit_galileo.lnk, galileo.dat.
• Routines for interactive fitting with MINUIT: fitter.f, fcn.f, set_plot_options.f, show_par.f, write_line.f, ps_output.f, fitter.lnk, ls_data.dat, ls_fit.min. A description and sample session of this program is given here, and there is also a plot of the fit: ps, pdf.
• Routines for fitting with MINUIT from PAW with vec/fit: vecfit.kumac, fcn_vecfit.f. Here is some sample data, vecfit_data.dat, and a plot of the fit.
• Materials from the tutorial 13.12.99 at Royal Holloway:
  • The program rambo.f by Kleiss, Stirling and Ellis to generate events uniformly distributed in phase space (needed for the test routines below).
  • A test routine for row-wise ntuples test_rwn.f, and linking script test_rwn.lnk. Look at the ntuple with PAW or read it in with read_rwn.f, read_rwn.lnk. You may want to consult the ntuple section of the HBOOK manual.
  • A test routine for column-wise ntuples test_cwn.f, and linking script test_cwn.lnk. Look at the ntuple with PAW or read it in with read_cwn.f, read_cwn.lnk.
  • The program generate_decays.f for generating 3-body decays according to a chosen matrix element. Needs m2_0_minus.f, m2_1_minus.f, rambo.f, generate_decays.lnk.
  • The program decay_anl.f for analyzing the ntuples produced by generate_decays.f. Needs read_cwn_setup.f, m2_0_minus.f, m2_1_minus.f, rambo.f, decay_anl.lnk.
  • The program fit_dalitz for fitting the relative contributions of 3-body decays of 0- and 1- mesons. The main program is fitter.f, the same as above. Needs fcn_dalitz.f, read_cwn_setup.f, m2_0_minus.f, m2_1_minus.f, set_plot_options.f, show_par.f, write_line.f, ps_output.f, fit_dalitz.lnk, dalitz.min.
  • An ntuple decay_data.hbook containing the momentum vectors from an unknown mixture of 1000 0- and 1- meson decays.
• Information on the neural network program JETNET: The online manual, and the code for JETNET version 3.1. Here is a short test routine test_jetnet.f, which needs generate_xy.f, test_jetnet.lnk. Some HBOOK histograms generated using 2 input nodes, 2 layers and 3 hidden nodes are in test_jetnet.his.
