Pollution analysis flawed by statistical model

Flawed trials, flawed analysis: why CBP should avoid rating itself.

The views expressed in this editorial are in part derived from discussion that took place during March, 2006, among the individuals who make up the Technique Consortium. This is an intercollegiate group, consisting of technique department chairs and technique instructors, that meets once a year under the auspices of the Association of Chiropractic Colleges. Despite the benefit provided by the i...

A Hybrid Deterministic-Statistical Model Integrating Economic, Meteorological and Environmental Variables to Air Pollution

The following study is based on a hybrid statistical-deterministic model designed for the assessment of the daily concentration of sulfur dioxide, carbon monoxide  and particulate matter (PM10) as major pollutants in the Greater Tehran Area (GTA): the capital of Iran. The model uses three available or assessable variables including economic, meteorological and environmental in the GTA for the y...

Statistical analysis of air pollution panel studies: an illustration.

PURPOSE The panel study design is commonly used to evaluate the short-term health effects of air pollution. Standard statistical methods are available for analyzing longitudinal data, but the literature reveals that these methods are poorly understood by practitioners. METHODS We review standard statistical methods for modeling longitudinal data. Marginal, conditional, and transitional approa...

Flawed analysis, implausible results--move on.

Multivariate Statistical Analysis and Environmental Modeling of Heavy Metals Pollution by Industries

This study presents the application of some selected multivariate statistical techniques, prediction method, and confirmatory analysis to identify spatial variation and pollution sources of the Jakara-Getsi river system in Kano, Nigeria. Two-hundred and forty water samples were collected from eight different sampling sites along the river system. Fifteen physico-chemical parameters were analyze...
