HANDBOOK OF FORENSIC STATISTICS by David L Banks( )

3 editions published between 2020 and 2021 in English and held by 77 WorldCat member libraries worldwide

Handbook of Forensic Statistics is a collection of chapters by leading authorities in forensic statistics. Written for statisticians, scientists, and legal professionals having a broad range of statistical expertise, it summarizes and compares basic methods of statistical inference (frequentist, likelihoodist, and Bayesian) for trace and other evidence that links individuals to crimes, the modern history and key controversies in the field, and the psychological and legal aspects of such scientific evidence. Specific topics include uncertainty in measurements and conclusions; statistically valid statements of weight of evidence or source conclusions; admissibility and presentation of statistical findings; and the state of the art of methods (including problems and pitfalls) for collecting, analyzing, and interpreting data in such areas as forensic biology, chemistry, and pattern and impression evidence. The particular types of evidence that are discussed include DNA, latent fingerprints, firearms and toolmarks, glass, handwriting, shoeprints, and voice exemplars
A Biweight Approach to the One-Sample Problem by Karen Kafadar( Book )

3 editions published between 1979 and 1982 in English and held by 4 WorldCat member libraries worldwide

A 't'-like statistic, replacing the classical mean by a biweight in the numerator and the sample variance by a corresponding variance term in the denominator that modifies that used by Gross is proposed and evaluated for its efficiency in constructing confidence intervals in stretched-tailed situations. For the case of many samples of common population width, the method of borrowing estimates of the variance of the numerator via root-mean-squares is considered. The one-sample bi-weight-'t' is shown, via Monte Carlo simulations, to be very efficient for samples of moderate sizes (in terms of expected length of the confidence interval), and combining variance estimates in the denominator is useful when the underlying distribution of the sample is not extremely long-tailed.

Robust confidence intervals for the one- and two-sample problems by Karen Kafadar( )

Using Biweights in the Two-Sample Problem by Karen Kafadar( Book )

2 editions published in 1979 in English and held by 3 WorldCat member libraries worldwide

It is proposed to replace the usual Student's-t statistic which tests for equality of means of two distributions and to construct a confidence interval for the difference by a biweight-'t' statistic. The biweight-'t' is a ratio of the difference of the biweight estimates of location from the two samples to a standard error of this difference. Three different forms of the denominator are evaluated. Monte Carlo simulations reveal that resulting confidence intervals are highly efficient in moderate sample sizes, and that nominal levels are nearly attained, even when considering extreme percentage points

A Robust Confidence Interval for Samples of Five Observations by Karen Kafadar( Book )

2 editions published in 1979 in English and held by 2 WorldCat member libraries worldwide

A robust confidence interval using biweights for the case of five observations is proposed when the underlying distribution has somewhat heavier tails than the Gaussian. The distribution of a t-like statistic is approximated by a Student's t on the nominal four degrees of freedom using different scale factors which depend upon the value of the biweight weights. Results given by Monte Carlo simulations indicate that, even for very high coverage probabilities, the intervals proposed are highly efficient, in terms of the expected length of the confidence interval.

Formulas for a Two-Sample Monte Carlo Swindle by Karen Kafadar( Book )

2 editions published in 1979 in English and held by 2 WorldCat member libraries worldwide

In order to obtain accurate estimates of the percentage points of the two-sample t-like statistic, we use a Monte Carlo swindle based on the method of conditional probabilities. The formulas for this implementation are described in this report. (Author)
The effects of non-Gaussian noise and different boundary rules on two-dimensional linear and nonlinear smoothers by Markus Emsermann( Book )

A Retrievable Recipe for Inverse 't' by Donald Paul Gaver( Book )

2 editions published in 1984 in English and held by 2 WorldCat member libraries worldwide

A simple formula is first presented for the student t percent points that has the virtue of being easily re-derived from scratch: it is retrievable. It is also quite accurate, but improvements are also presented, as is a stand-alone formula (no normal tables need be applied!). (Author)
