Structured data analysis (statistics)
Encyclopedia
Structured data analysis is the statistical data analysis
of structured data. This can arise either in the form of an a priori structure such as multiple-choice questionnaires or in situations with the need to search for structure
that fits the given data, either exactly or approximately. This structure can then be used for making comparisons, predictions, manipulations etc.
Statistics
Statistics is the study of the collection, organization, analysis, and interpretation of data. It deals with all aspects of this, including the planning of data collection in terms of the design of surveys and experiments....

Structure
Structure is a fundamental, tangible or intangible notion referring to the recognition, observation, nature, and permanence of patterns and relationships of entities. This notion may itself be an object, such as a built structure, or an attribute, such as the structure of society...

Types of structured data analysis
- Regression analysisRegression analysisIn statistics, regression analysis includes many techniques for modeling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables...
- Bayesian analysisHierarchical Bayes modelThe hierarchical Bayes model is a method in modern Bayesian statistical inference. It is a framework for describing statistical models that can capture dependencies more realistically than non-hierarchical models....

- Combinatorial data analysisCombinatorial data analysisCombinatorial data analysis is the study of data sets where the arrangement of objects is important. CDA can be used either to determine how well a given combinatorial construct reflects the observed data, or to search for a suitable combinatorial construct that does fit the data.-See...
- Geometric data analysisGeometric data analysisGeometric data analysis can refer to geometric aspects of image analysis, pattern analysis and shape analysis or the approach of multivariate statistics that treats arbitrary data sets as clouds of points in n-dimensional space...

- Shape analysisStatistical shape analysisStatistical shape analysis is a geometrical analysis from a set of shapes in which statistics are measured to describe geometrical properties from similar shapes or different groups, for instance, the difference between male and female Gorilla skull shapes, normal and pathological bone shapes, etc...

- Tree structured data analysisDecision tree learningDecision tree learning, used in statistics, data mining and machine learning, uses a decision tree as a predictive model which maps observations about an item to conclusions about the item's target value. More descriptive names for such tree models are classification trees or regression trees...
- Formal concept analysisFormal concept analysisFormal concept analysis is a principled way of automatically deriving an ontology from a collection of objects and their properties. The term was introduced by Rudolf Wille in 1984, and builds on applied lattice and order theory that was developed by Birkhoff and others in the 1930s.-Intuitive...
