Multivariate Data Analysis of Proteome Data

2006
We present the background for multivariate data analysis on proteomics data with a hands-on section on how to transfer data between different software packages. The techniques can also be used for other biological and biochemical problems in which structures have to be found in a large amount of data. Digitalization of the 2D gels, analysis using image

Multivariate Data and Multivariate Analysis

2005
Multivariate data arise when researchers record the values of several random variables on a number of subjects or objects or perhaps one of a variety of other things (we will use the general term “units”) in which they are interested, leading to a vector-valued or multidimensional observation for each.

Multivariate Data Analysis

2016
This short chapter shows how the statistical properties of higher-dimensional data can be visualized: with 3D-surfaces, Scatterplot Matrices, and Correlation Matrices.

Multivariate Analysis of Incomplete Mapped Data

Transactions in GIS, 2003
AbstractClassical multivariate analyses are based on matrix algebra and enable the analysis of a table containing measurements of a set of variables for a set of sites. Incomplete mapped data consist of measurements of a set of variables recorded for the same geographical region but for different zonal systems and with only a partial sampling of this ...

Multivariate Entropy Analysis of Network Data

Bulletin of Sociological Methodology/Bulletin de Méthodologie Sociologique, 2015
Multigraphs with numerical or qualitative attributes defined on vertices and edges can benefit from systematic methods based on multivariate entropies for describing and analysing the interdependencies that are present between vertex and edge attributes. This is here illustrated by application of these tools to a subset of data on the social relations

Multivariate data analysis of multivariate populations

Chemometrics and Intelligent Laboratory Systems, 2007
For data that can be arranged in populations, multivariate data analysis of digitalized distributions is suggested as an alternative method to detect variations. This approach includes a representation of the data that avoids information destroying pre-processing such as averaging.

Multivariate Data Analysis

Different chapters within this book and the literature prove the ToF-SIMS as a powerful surface analysis tool. However, one large drawback is that data analysis can be challenging and is very time-consuming compared to the measurement time and to other analysis techniques. Often only a small subset of data is analysed, e.g.

Multivariate Data Analysis

1975
Abstract : This paper contains an account of several techniques in multivariate data analysis. Included among these techniques are classification and clustering procedures, multidimensional contingency table analysis, and some graphical representation techniques. Some data bases are employed to illustrate the techniques.

Multidimensional Fitting for Multivariate Data Analysis

Journal of Computational Biology, 2010
Large multidimensional data matrices are frequent in biology. However, statistical methods often have difficulties dealing with such matrices because they contain very complex data sets. Consequently variable selection and dimensionality reduction methods are often used to reduce matrix complexity, although at the expense of information conservation. A
