  2. Coefficient of determination - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_determination

    Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).

  3. Retardation factor - Wikipedia

    en.wikipedia.org/wiki/Retardation_factor

    An R F value will always be in the range 0 to 1; if the substance moves, it can only move in the direction of the solvent flow, and cannot move faster than the solvent. For example, if particular substance in an unknown mixture travels 2.5 cm and the solvent front travels 5.0 cm, the retardation factor would be 0.50.

  4. Regulatory focus theory - Wikipedia

    en.wikipedia.org/wiki/Regulatory_focus_theory

    Regulatory fit intensifies responses, such as the value of a chosen object, persuasion, and job satisfaction. [ 4 ] Regulatory fit does not increase the assessment of a decision ; instead when someone feels "right" about their decision, the experience of "correctness and importance" is transferred to the ensuing assessment of the chosen object ...

  5. Minnesota Multiphasic Personality Inventory - Wikipedia

    en.wikipedia.org/wiki/Minnesota_Multiphasic...

    A new addition to the validity scales for the MMPI-2-RF includes an over reporting scale of somatic symptoms (F S) as well as revised versions of the validity scales of the MMPI-2 (VRIN-r, TRIN-r, F-r, F P-r, FBS-r, L-r, and K-r). The MMPI-2-RF does not include the S or F B scales, and the F-r scale now covers the entirety of the test. [48]

  6. Effect size - Wikipedia

    en.wikipedia.org/wiki/Effect_size

    In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...

  7. Dimensional models of personality disorders - Wikipedia

    en.wikipedia.org/wiki/Dimensional_models_of...

    Dimensional models are intended to reflect what constitutes personality disorder symptomology according to a spectrum, rather than in a dichotomous way.As a result of this they have been used in three key ways; firstly to try to generate more accurate clinical diagnoses, secondly to develop more effective treatments and thirdly to determine the underlying etiology of disorders.

  8. Degrees of freedom (statistics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom...

    the regression (not residual) degrees of freedom in linear models are "the sum of the sensitivities of the fitted values with respect to the observed response values", [11] i.e. the sum of leverage scores. One way to help to conceptualize this is to consider a simple smoothing matrix like a Gaussian blur, used to mitigate data noise. In ...

  9. Incremental validity - Wikipedia

    en.wikipedia.org/wiki/Incremental_validity

    Incremental validity is a type of statistical validity that assesses whether a new psychometric assessment has more predictive ability than existing methods of assessment. [1]
