Social Foundations of Self II: The Generalized Other

267
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group...

Generalized Hooke's Law

2.8K
The generalized Hooke's Law is a broadened version of Hooke's Law, which extends to all types of stress and in every direction. Consider an isotropic material shaped into a cube subjected to multiaxial loading. In this scenario, normal stresses are exerted along the three coordinate axes. As a result of these stresses, the cubic shape deforms into a rectangular parallelepiped. Despite this deformation, the new shape maintains equal sides, and there is a normal strain in the direction of the...

Generalized Anxiety Disorder01:30

Generalized Anxiety Disorder

731
Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Generalization, Discrimination, and Extinction01:24

Generalization, Discrimination, and Extinction

1.4K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Linear Circuits01:17

Linear Circuits

882
A linear circuit is characterized by its output having a direct proportionality to its input, adhering to the linearity property, which encompasses the principles of homogeneity (scaling) and additivity. Homogeneity dictates that when the input, also referred to as the excitation, is multiplied by a constant factor, the output, known as the response, is correspondingly scaled by the same constant factor. For instance, if the current is multiplied by a constant 'k,' the voltage likewise...

Area of Science:

  • Statistics
  • Econometrics
  • Machine Learning

Background:

  • Generalized linear models (GLMs) are widely used for statistical prediction.
  • Assessing the predictive power of these models is crucial for reliable inference.
  • Existing measures may not adequately capture predictive performance, especially in complex scenarios.

Purpose of the Study:

  • To investigate summary measures of predictive power for generalized linear models.
  • To introduce and evaluate a generalization of the multiple correlation coefficient for GLMs.
  • To compare different estimators of this generalized correlation measure.

Main Methods:

  • The study defines population and sample values for the generalized correlation coefficient.
  • Four estimators of the measure were compared based on bias and mean squared error.
  • Bootstrap methods were employed for confidence interval construction and assessing model selection bias.

Main Results:

  • The sample and jack-knife estimators generally performed adequately.
  • A cross-validation estimator exhibited significant negative bias and high mean squared error.
  • Bootstrap methods are effective for confidence intervals and evaluating optimism in model selection.

Conclusions:

  • The generalized correlation coefficient provides a valuable summary of predictive power in GLMs.
  • Careful selection of estimators is necessary, as some methods (e.g., cross-validation) can be unreliable.
  • Bootstrap techniques enhance the reliability of predictive power assessment and model selection evaluation.
