- Statistical tests
- H.Keutelian,
"The Kolmogorov-Smirnov statistic when
estimating parameters from data"
[Describes a simple Monte Carlo procedure to convert a
KS statistic into a probability when comparing a data sample
to a model in which one or more parameters have been
determined from the data.]
CDF note 1285, Version 1.0, April 30, 1991.
- L. Demortier,
"Assessing the significance of a deviation
in the tail of a distribution"
[Defines and investigates some properties of the
Kolmogorov-Smirnov, Smirnov-Cramer-von Mises and
Anderson-Darling statistics for one-sample and two-sample
tests.]
CDF note 3419, Version 1.0, November 20, 1995.
- A. Beretvas, M. Binkley,
L. Demortier,
"Binned KS probability"
[Studies the effect that binning a data sample has on the
conversion of a KS statistic into a probability. Especially
useful to interpret the results of the PAW command "diff".]
CDF note 4373, Version 2.0, November 25, 1997.
- Fitting techniques
- T. Devlin,
"Correlations from systematic corrections
to Poisson-distributed data in log-likelihood
functions"
[Describes how to incorporate the effect of systematic
uncertainties, background contamination and efficiency
corrections in Poisson likelihood fits.]
CDF note 3126, version 3.1, May 27, 1999.
- H. Keutelian,
"A procedure to apply multiple mass
constraints to a set of tracks"
CDF note 3565, February 21, 1996.
- Unfolding methods
- A. Robinson, P.K. Sinervo,
"Correcting the top quark pT
distribution"
[This analysis uses an unfolding method that's designed to
work with small numbers of events and with background.]
CDF note 4821, December 17, 1998.
- A. Bhatti, B. Flaugher,
"Inclusive jet cross section in pbar-p
collisions at sqrt(s)=1.8 TeV"
[Section 5 of this PRD describes the unfolding method.
It is designed to work with large numbers of events and no
background.]
CDF note 5291, version 4.0, June 24, 2000.
- Combining measurements
- R.J. Hollebeek, P.K. Sinervo,
H.H. Williams,
"The evaluation of upper limits for top
quark production using combined measurements"
[Defines upper limits according to classical and Bayesian
statistics, and descibes three methods to obtain a combined
upper limit from two or more measurements. Also describes how
to incorporate systematic uncertainties in the calculation of
upper limits. Although the authors clearly favor the frequentist
approach (often referring to it as "anti-Bayesian"), their
method of smearing with systematics is
Bayesian.]
CDF note 1109, January 6, 1990.
- M. Shochet,
"More on statistics of combined
measurements"
[Studies the three methods described in CDF note 1109 and
concludes that only one of them is robust.]
CDF note 1212, May 25, 1990.
- T. Liss, G. Unal, P.K. Sinervo,
"Estimating the statistical significance
of a top quark search counting experiment."
[Calculates the significance of the Run 1A top quark sample,
by combining the events observed in the dilepton and
tagged lepton+jets channels.]
CDF note 2370, Version 1.1, December 1, 1993.
- L. Demortier, R. Hughes,
R. Roser,
"Averaging the top quark mass measurements
from CDF and D0"
[The appendix describes the mathematical formalism used to
combine measurements. It is based on minimizing a chisquare
with a covariance matrix that includes statistical and
systematic uncertainties and their correlations.]
CDF note 4439, version 2.5, October 13, 1998.
- C. Grosso-Pilcher, G. Landsberg,
"Combined limits on first generation
leptoquarks from the CDF and D0 experiments"
[Does both a frequentist and Bayesian analysis.]
CDF note 4575, version 2.0, May 11, 1997.
- Confidence intervals and limits
- C. Blocker,
"Dilution factors"
[Discusses how the statistical uncertainty of a measurement
is affected by backgrounds, mistaggings and nonzero resolutions.
Applies mainly to asymmetry and mixing measurements.]
CDF note 3406, Version 1.1, December 12, 1995.
- J. Conway, K. Maeshima,
"Upper limits on Poisson processes
incorporating uncertainties in acceptance and
background"
CDF note 4476, Version 2, March 13, 1998.
- C. Blocker,
"Comment on the Feldman and Cousins
method of limits"
[How to set limits near physical boundaries; applied to
the sin(2beta) analysis.]
CDF note 4611, Version 1.0, May 27, 1998.
- Monte Carlo methods
- M. Mangano,
"The unweighting of matrix element Monte
Carlos"
CDF note 1665, January 1991.
