The report of results should include data, analysis, and presentation. Specifically, the data report should include the description of the flow of the patients through the study, as well as the number of patients included in each stage of the analysis and/or subgroup examined. The data report should provide distributions (including missing values) of basic demographic characteristics (e.g., sex and age), standard (disease-specific) prognostic... 

A discussion of the interpretation of enzyme activity banding patterns and the analysis of electrophoretic data is beyond the scope of this chapter. Details on the interpretation of zymograms can be found in several of the references cited herein.10 11 22 Richardson et a/.10 provide a thorough discussion of data analysis and present several detailed examples of analyses taken from the literature. Among the major computer software packages currently available for data analysis are BIOSYS-1 23 PAUP,24 PHYLIP,25... 

In operation, the linear-scan voltage generator sweeps the potential between the reference and working electrodes, and the current in the cell is monitored by op amp C. The output voltage of op amp B, which is proportional to the current I in the cell, is recorded or acquired by a computer for data analysis and presentation. ... 

Caldwell [4] describes a useful method of data analysis and presentation of multiple variable data sets to provide discovery teams with predictions of oral bioavailability. By ranking the compounds as high, intermediate, and low for in vitro solubility, acidic stability (to simulate stomach), hepatocyte stability (to simulate liver), and Caco-2 permeability, reliable early predictions can be made for in vivo oral bioavailability.

A database is a collection of related facts or data that has been designed, built and populated with data for a specific purpose (Elmasri and Navathe, 1994). We are here concerned with computerised databases on accidents and near accidents. These are electronic archives, containing a record of the essential facts about each unwanted event at the company. The purpose of storing the data electronically rather than in a paper-based archive is to make it easier to retrieve, analyse and present the data. Computer support also offers new possibilities for data analysis and presentation. 

A variety of methods have been developed by mathematicians and computer scientists to address this task, which has become known as data mining (see Chapter 9, Section 9.8). Fayyad defined and described the term data mining as the nontrivial extraction of impHcit, previously unknown and potentially useful information from data, or the search for relationships and global patterns that exist in databases [16]. In order to extract information from huge quantities of data and to gain knowledge from this information, the analysis and exploration have to be performed by automatic or semi-automatic methods. Methods applicable for data analysis are presented in Chapter 9. 

Documentation of the system design and operating data, analytical assumptions and constraints used in the analysis in a notebook becomes part of the QA record. However, it is useful to have documents analyses and records as computer files for handling the voluminous data reporting and presenting the results of the work. It provides. 

The objective of this notebook was the collection, analysis, and presentation of nonelectronic component failure data and the presentation of analytical methods that form the state-of-the-art in nonelectronic reliability analysis. This report replaces the former Nonelectronic Reliability Notebook (RADC-TR-75-22). 

Toward these ends, the kinetics of a wider set of reaction schemes is presented in the text, to make the solutions available for convenient reference. The steady-state approach is covered more extensively, and the mathematics of other approximations ( improved steady-state and prior-equilibrium) is given and compared. Coverage of data analysis and curve fitting has been greatly expanded, with an emphasis on nonlinear least-squares regression. 

Prediction of the useful life, or the remaining life, of coatings from physical or analytical measurements presents many problems in data analysis and interpretation. Two important considerations are that data must be taken over a long period of time, and the scatter from typical paint tests is large. These considerations require innovative application of statistical techniques to provide adequate prediction of the response variables of interest. 

With reference to Fig. 4, this section presents several examples that demonstrate how various technologies can be assembled into data analysis and interpretation systems in practical application. 

Another form of artificial intelligence is realized in artificial neural networks (ANN). The principle of ANNs has been presented in Sect. 6.5. Apart from calibration, data analysis and interpretation is one of the most important fields of application of ANNs in analytical chemistry (Tusar et al. [1991] Zupan and Gasteiger [1993]) where two branches claim particular interest ... 

Automation and data collection from complex laboratory equipment have been accomplished. The result of this effort has been more efficient use of the researcher s time, Improved data analysis and the capability to easily conduct lengthy experiments without personnel being present. 

The SAP will have detailed the precise methods of analysis and presentation and should ideally be finalised well before database lock. This enables work to begin in good time on the programming of the analyses. These programs will be tested on dirty data from the trial, so that they can be pretty much finalised before the trial ends, enabling, at least in theory, rapid turnaround of the key analyses. 

Design Qualification, DQ, is about specifying what the instrument or instrument system has to do. This would include documenting technical requirements, environmental conditions, sample and sample presentation requirements, data acquisition and presentation needs, operability factors and any Health Safety issues. In addition a cost-benefit analysis would normally be performed.
