What is "quantitative analysis"

Analysis \A*nal"y*sis\, n.; pl. Analyses. [Gr. ?, fr. ? to unloose, to dissolve, to resolve into its elements; ? up + ? to loose. See Loose.]

1. A resolution of anything, whether an object of the senses or of the intellect, into its constituent or original elements; an examination of the component parts of a subject, each separately, as the words which compose a sentence, the tones of a tune, or the simple propositions which enter into an argument. It is opposed to synthesis.

2. (Chem.) The separation of a compound substance, by chemical processes, into its constituents, with a view to ascertain either

   1. what elements it contains, or

   2. how much of each element is present. The former is called qualitative, and the latter quantitative analysis.

3. (Logic) The tracing of things to their source, and the resolving of knowledge into its original principles.

4. (Math.) The resolving of problems by reducing the conditions that are in them to equations.

5. 1. A syllabus, or table of the principal heads of a discourse, disposed in their natural order.

   2. A brief, methodical illustration of the principles of a science. In this sense it is nearly synonymous with synopsis.

6. (Nat. Hist.) The process of ascertaining the name of a species, or its place in a system of classification, by means of an analytical table or key.

   Ultimate, Proximate, Qualitative, Quantitative, and Volumetric analysis. (Chem.) See under Ultimate, Proximate, Qualitative, etc.

n. (context chemistry English) The determination of the amounts of an element or compound in a sample.

n. chemical analysis to determine the amounts of each element in the substance [syn: quantitative chemical analysis]

Quantitative analysis may refer to:

• Quantitative analysis (finance), an analysis technique applying mathematics (stochastic calculus) to finance
• Quantitative analysis (chemistry), in analytical chemistry, the measurements of quantities of substances produced in reactions rather than simply noting the nature of the reactions
• Quantitative analysis of behavior, quantitative models in the experimental analysis of behavior
• Mathematical psychology, an approach to psychological research using mathematical modeling of perceptual, cognitive and motor processes
• Statistics, the collection, organization, analysis, interpretation and presentation of data, in social science

In analytical chemistry, Quantitative Analysis is the determination of the absolute or relative abundance (often expressed as a concentration) of one, several or all particular substance(s) present in a sample.

Quantitative analysis is the use of models, or algorithms, to evaluate assets for investment. The process usually consists of searching vast databases for patterns, such as correlations among liquid assets or price-movement patterns ( trend following or mean reversion). The resulting strategies may involve high-frequency trading.

Some of the larger investment managers using quantitative analysis include Renaissance Technologies, Winton Capital Management, D. E. Shaw & Co., AQR Capital Management, and Two Sigma Investments.
