The GMM estimators are known to be consistent, asymptotically normal, and most efficient in the class of all estimators that do not use any extra information aside from that contained in the moment conditions. GMM were advocated by Lars Peter Hansen in 1982 as a generalization of the method of moments, [2] introduced by Karl Pearson in 1894 ...
The EM algorithm consists of two steps: the E-step and the M-step. Firstly, the model parameters and the () can be randomly initialized. In the E-step, the algorithm tries to guess the value of () based on the parameters, while in the M-step, the algorithm updates the value of the model parameters based on the guess of () of the E-step.
Therefore, generalization is a valuable and integral part of learning and everyday life. Generalization is shown to have implications on the use of the spacing effect in educational settings. [13] In the past, it was thought that the information forgotten between periods of learning when implementing spaced presentation inhibited generalization ...
Self-assessment in education technology relies on students analyzing their strengths, weaknesses, and areas where improvement is possible to set realistic goals in learning, improve their educational performances and track their progress. [258] [259] One of the unique tools for self-assessment made possible by education technology is Analytics.
The ISTE Standards, formerly known as the National Educational Technology Standards (NETS), are standards for the use of technology in teaching and learning (technology integration). [1] They are published by the International Society for Technology in Education (ISTE), a nonprofit membership association for educators focused on educational ...
In econometrics, the Arellano–Bond estimator is a generalized method of moments estimator used to estimate dynamic models of panel data.It was proposed in 1991 by Manuel Arellano and Stephen Bond, [1] based on the earlier work by Alok Bhargava and John Denis Sargan in 1983, for addressing certain endogeneity problems.

The study of stability gained importance in computational learning theory in the 2000s when it was shown to have a connection with generalization. [1] It was shown that for large classes of learning algorithms, notably empirical risk minimization algorithms, certain types of stability ensure good generalization.
The educational system [1] generally refers to the structure of all institutions and the opportunities for obtaining education within a country. It includes all pre-school institutions, starting from family education, and/or early childhood education, through kindergarten, primary, secondary, and tertiary schools, then lyceums, colleges, and faculties also known as Higher education (University ...
