  2. 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).

  3. Causal graph - Wikipedia

    en.wikipedia.org/wiki/Causal_graph

    In statistics, econometrics, epidemiology, genetics and related disciplines, causal graphs (also known as path diagrams, causal Bayesian networks or DAGs) are probabilistic graphical models used to encode assumptions about the data-generating process. Causal graphs can be used for communication and for inference.

  4. Psychological statistics - Wikipedia

    en.wikipedia.org/wiki/Psychological_statistics

    Confirmatory Factor Analysis (CFA) is a factor analytic technique that begins with a theory and test the theory by carrying out factor analysis. The CFA is also called as latent structure analysis, which considers factor as latent variables causing actual observable variables. The basic equation of the CFA is X = Λξ + δ

  5. Structural equation modeling - Wikipedia

    en.wikipedia.org/wiki/Structural_equation_modeling

    Exploratory and confirmatory factor analysis models, for example, focus on the causal measurement connections, while path models more closely correspond to SEMs latent structural connections. Modelers specify each coefficient in a model as being free to be estimated, or fixed at some value.

  6. Psychometrics - Wikipedia

    en.wikipedia.org/wiki/Psychometrics

    Factor analysis, multidimensional scaling, and cluster analysis are all multivariate descriptive methods used to distill from large amounts of data simpler structures. More recently, structural equation modeling [21] and path analysis represent more sophisticated approaches to working with large covariance matrices. These methods allow ...

  7. Mediation (statistics) - Wikipedia

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

    Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...

  8. Path analysis - Wikipedia

    en.wikipedia.org/wiki/Path_analysis

    Path Analysis may refer to: Path analysis (statistics), a statistical method of testing cause/effect relationships; Path analysis (computing), a method for finding the trail that leads users to websites; Critical path method, an operations research technique; Main path analysis, a method for tracing the most significant citation chains in a ...

  9. Path dependence - Wikipedia

    en.wikipedia.org/wiki/Path_dependence

    Path dependence is a concept in the social sciences, referring to processes where past events or decisions constrain later events or decisions. [1] [2] It can be used to refer to outcomes at a single point in time or to long-run equilibria of a process. [3]
