  2. Dependent and independent variables - Wikipedia

    en.wikipedia.org/wiki/Dependent_and_independent...

    An example is provided by the analysis of trend in sea level by Woodworth (1987). Here the dependent variable (and variable of most interest) was the annual mean sea level at a given location for which a series of yearly values were available. The primary independent variable was time.

  3. Path analysis (statistics) - Wikipedia

    en.wikipedia.org/wiki/Path_analysis_(statistics)

    In statistics, path analysis is used to describe the directed dependencies among a set of variables. This includes models equivalent to any form of multiple regression analysis, factor analysis, canonical correlation analysis, discriminant analysis, as well as more general families of models in the multivariate analysis of variance and covariance analyses (MANOVA, ANOVA, ANCOVA).

  4. Primary sector of the economy - Wikipedia

    en.wikipedia.org/wiki/Primary_sector_of_the_economy

    The primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, logging, fishing, forestry and mining. [ 1 ] [ 2 ] [ 3 ] The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries .

  5. Factor analysis - Wikipedia

    en.wikipedia.org/wiki/Factor_analysis

    Factor analysis is an interdependence technique. The complete set of interdependent relationships is examined. There is no specification of dependent variables, independent variables, or causality. Factor analysis assumes that all the rating data on different attributes can be reduced down to a few important dimensions.

  6. Secondary sector of the economy - Wikipedia

    en.wikipedia.org/wiki/Secondary_sector_of_the...

    Countries that primarily produce agricultural and other raw materials (i.e., primary sector) tend to grow slowly and remain either under-developed or developing economies. The value added through the transformation of raw materials into finished goods reliably generates greater profitability , which underlies the faster growth of developed ...

  7. Derived demand - Wikipedia

    en.wikipedia.org/wiki/Derived_demand

    In economics, derived demand is demand for a factor of production or intermediate good that occurs as a result of the demand for another intermediate or final good. [1] In essence, the demand for, say, a factor of production by a firm is dependent on the demand by consumers for the product produced by the firm.

  8. Principal component regression - Wikipedia

    en.wikipedia.org/wiki/Principal_component_regression

    In PCR, instead of regressing the dependent variable on the explanatory variables directly, the principal components of the explanatory variables are used as regressors. One typically uses only a subset of all the principal components for regression, making PCR a kind of regularized procedure and also a type of shrinkage estimator.

  9. Path dependence - Wikipedia

    en.wikipedia.org/wiki/Path_dependence

    Path dependence has primarily been used in comparative-historical analyses of the development and persistence of institutions, whether they be social, political, or cultural. There are arguably two types of path-dependent processes: One is the critical juncture framework, most notably utilized by Ruth and David Collier in political science.
