Descriptive Statistical Techniques,se air pollutant concentrations in the city do not have a fixed value but vary from one place to another. They also vary with respect to time. Similar considerations apply in the assessment of water quality in a river in terms of, say, the level of nitrogen or number of faecal coliforms present, or

Environmetric Methods of Nonstationary Time-Series Analysis: Univariate Methods,we consider a particular class of environmetric methods; namely the analysis of environmental time-series. Although such time-series can be obtained from planned experiments, they are more often obtained by passively monitoring the environmental variables over long periods of time. Not surprisingly,

Regression and Correlation, always pattern in the data, obscured to a greater or lesser extent by random variation. Both pattern and randomness can be summarized by statistical methods, but their relative importance and the eventual summary depend on the aim of the analysis. At one extreme are techniques intended solely to ex

Factor and Correlation Analysis of Multivariate Environmental Data,r. Thus, it is essential to have mathematical techniques that permit the study of the simultaneous variation of multiple variables. One such analysis is based on examining the relationships between pairs of variables. This correlation analysis, however, does not provide a clear view of the multiple

Errors and Detection Limits,is taken. As this measurement error can influence the subsequent conclusions drawn from the analysis of the data, it is essential to identify, reduce and minimise the effects of the errors wherever possible. This procedure requires that we have a thorough knowledge of the measurement process and imp

Visual Representation of Data Including Graphical Exploratory Data Analysis,nterpret their real meaning. . An excellent example of this is shown in Fig. 1, which shows a series of plots of data sets, all of which have correlation coefficients, some of which apparently indicate reasonably strong correlation. However, the plots reveal clearly the dangers of relying only on nu

Philip K. Hopketo provide a framework for reusability. He thus identifies some particular frames, such as the translation frame (e.g., a compiler), the information system frame, the control frame (or reactive system frame), .... Each frame is described along three viewpoints that are application domains, requireme
