This is considered a minimum requirement of a statistical matching procedure, and can be easily ascertained by specific tests/ indexes for similarity of distributions 31 Jan 2005 Automatic indexing research by Gerard Salton of Cornell University and others in the 1970s and 1980s evolved into statistical processing RQ3: Does combination of statistical associative and lexical approaches improve indexing performance, es- pecially for settings with concept drift?

Indexing is broadly referred to as an indicator or measure of something. In the financial markets, indexing can be used as a statistical measure for tracking economic data, a methodology for
For the statistical approaches, many research works have been proposed such as probabilistic latent semantic indexing  and latent Dirichlet allocation , This approach to the problem of automatic indexing is a statistical one. It is based on the rather straightforward notion that the indi- vidual words in a document Since modern data analyses almost always involve graphical assessments of relationships and assumptions, links to appropriate graphical methods are provided The real goal of an indexing approach is to be a "guidance system" to the body of While there is statistical fluctuation in the value of the constant it is a
Quantitative data analysis requires the construction of two types of measures of variables--indices and scales. These measures are frequently used and are important since social scientists often study variables that possess no clear and unambiguous indicators--for instance, age or gender.
Abstract: Automatic linguistic indexing of pictures is an important but highly challenging problem for researchers in computer vision and content-based image retrieval. In this paper, we introduce a statistical modeling approach to this problem. Categorized images are used to train a dictionary of hundreds of statistical models each representing a concept. An index number is a statistical derives to measure changes in the value of money. It is a number which represents the average price of a group of commodities at a particular time in relation to the average price of the same group of commodities at another time. Statistical Methods and Applications (SMA) is the official Journal of the Italian Statistical Society. This international journal fosters the development of statistical methodology and its applications in biological, demographic, economic, health, physical, social, and other scientific domains.

One approach to combining items is to calculate an index variable via an optimally-weighted linear combination of the items, called the Factor Scores. Each item’s weight is its factor loading. So each item’s contribution to the factor score depends on how strongly it relates to the factor. If one has a set of replicate diversity indices from two or more sites, e.g., where one calculated the diversity index for each sample, then these numbers are, mathematically, simply observations Quantitative data analysis requires the construction of two types of measures of variables--indices and scales. These measures are frequently used and are important since social scientists often study variables that possess no clear and unambiguous indicators--for instance, age or gender. Statistic approach – stores a single statistics, such as how often each word occurs in an item – used for generating relevance scores after a Boolean search . Probabilistic indexing - stores the information that are used in calculating a probability that a particular item satisfies (i.e., is relevant to) a particular query. Indexing is broadly referred to as an indicator or measure of something. In the financial markets, indexing can be used as a statistical measure for tracking economic data, a methodology for The cost of expert analysis to create subject indexing is not easily compared to the cost of hardware, software and labor to manufacture a comparable set of full-text, fully searchable materials.
