Statistical considerations in the interpretation of negative carcinogenicity data

Regulatory Toxicology and Pharmacology, 1989
The regulation of toxic substances present in the environment requires that carcinogens be distinguished from noncarcinogens on the strength of the available toxicological and epidemiological evidence for carcinogenicity. In this article, we consider the difficulties associated with establishing strong evidence against carcinogenicity.

Simplified Methods for Statistical Interpretation of Monitoring Data

Journal of the Air Pollution Control Association, 1972
Statistical techniques are useful for interpretation of monitoring data for pollutants, process variables, etc. Simplified nomographical methods are presented for relating numbers of samples to confidence intervals for their mean values, and for determining the proportion of the population exceeding a specified concentration and confidence intervals ...

Statistical Interpretation of Toxicity Data

1987
Many of the topics discussed in this chapter pertain to experimental data in general, but the context of their use and examples given are in the field of toxicology. The discussion focuses on the statistical interpretation of data rather than on the statistical procedures used in the data analysis.

Statistical approaches to interpretation of seismic reflection data

Tectonophysics, 2000
Abstract Statistical approaches offer a potentially powerful tool for interpretation of the complex seismic reflection patterns typically recorded from the crystalline crust. These methods focus on characterization of the complexity, scaling characteristics and spatial variability of the wave field with the ultimate aim of recovering information on ...

Interpretation of research data: Selected statistical procedures

American Journal of Health-System Pharmacy, 1980
Selected statistical procedures used in the analysis of research data are presented. The relationship of significance testing to research hypotheses is explained in terms of tests of differences and correlation. Also, the differences, assumptions, and advantages and disadvantages of parametric and nonparametric statistics are discussed.

A statistical interpretive method for neuropsychological test data.

Neuropsychology review, 2001
The accurate interpretation of large numbers of neuropsychological tests within a flexible battery approach is a difficult and sometimes controversial process. We present a statistically based method of interpretation (Rohling's Interpretive Method or RIM) and evaluation of neuropsychological data that allows for varying numbers of tests along a ...

Statistical interpretation of S-on-1 data and the damage initiation mechanism

SPIE Proceedings, 2008
ABSTRACT Multipulse laser induced damage optical materials is an important topic for many applications of nonlinear crystals. We studied multi pulse damage in X-cut KTiOPO 4 . A 6ns Nd:YAG laser has been used with a weakly focused beam. A fatigue phenomenon has been observed and we try to clarif y the question whether or not this phenomenon necessarily

Statistical approach to range-data fusion and interpretation

Proceedings of the First Euromicro Workshop on Advanced Mobile Robots (EUROBOT '96), 2002
Making-use of multiple sensors is crucial for improvement of mobile robot navigation performance. The contribution introduces a problem of integrating noisy range-data by data fusion on signal/pixel level. This is performed for multiple sensors and different sensor positions into a common description of the environment. The paper deals with grid models,

HOSPITAL INFECTIONS AND THEIR CONTROL: PITFALLS IN THE INTERPRETATION OF STATISTICAL DATA*

Journal of the American Geriatrics Society, 1961
The problem of intra‐hospital infection has been the subject of world‐wide concern, and even controversy, during the past decade. The shift in emphasis to the institution as a nidus of spreading pathogens is, in part, the natural outcome of an abating conflict with the once insurmountable infections originating in the community.

Statistical Transformation and the Interpretation of Inpatient Glucose Control Data

Endocrine Practice, 2014
To introduce a statistical method of assessing hospital-based non-intensive care unit (non-ICU) inpatient glucose control.Point-of-care blood glucose (POC-BG) data from hospital non-ICUs were extracted for January 1 through December 31, 2011. Glucose data distribution was examined before and after Box-Cox transformations and compared to normality ...
