Friedrich Maria Urban
Friedrich Maria Urban (born Friedrich Johann Victor Urban, 28 December 1878, Brünn, Austro-Hungarian Empire – 4 May 1964, Paris) was a psychologist from the Austro-Hungarian Empire, known for the introduction of probability weightings used in experimental psychology. Biography Friedrich Johann Victor Urban was born into a German-speaking family in the Austro-Hungarian empire. He adopted the name "Friedrich Maria" as a pen name and his published articles appear under the name "F. M. Urban". He was a Gymnasium graduate in Brünn in 1897 and received his '' Promotion'' (Ph.D.) in philosophy from the University of Vienna in 1902. He did research and studied probability under Wilhelm Wirth in Leipzig. He taught psychological acoustics at Harvard University from February 1904 to November 1905.

Item Response Theory
In psychometrics, item response theory (IRT) (also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables. It is a theory of testing based on the relationship between individuals' performances on a test item and the test takers' levels of performance on an overall measure of the ability that item was designed to measure. Several different statistical models are used to represent both item and test taker characteristics. Unlike simpler alternatives for creating scales and evaluating questionnaire responses, it does not assume that each item is equally difficult. This distinguishes IRT from, for instance, Likert scaling, in which ''"''All items are assumed to be replications of each other or in other words items are considered to be parallel instruments".A. van Alphen, R. Halfens, A. Hasman and T. Imbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Probit
In probability theory and statistics, the probit function is the quantile function associated with the standard normal distribution. It has applications in data analysis and machine learning, in particular exploratory statistical graphics and specialized regression modeling of binary response variables. Mathematically, the probit is the inverse of the cumulative distribution function of the standard normal distribution, which is denoted as \Phi(z), so the probit is defined as :\operatorname(p) = \Phi^(p) \quad \text \quad p \in (0,1). Largely because of the central limit theorem, the standard normal distribution plays a fundamental role in probability theory and statistics. If we consider the familiar fact that the standard normal distribution places 95% of probability between −1.96 and 1.96, and is symmetric around zero, it follows that :\Phi(-1.96) = 0.025 = 1-\Phi(1.96).\,\! The probit function gives the 'inverse' computation, generating a value of a standard normal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regression Line
In statistics, linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables). The case of one explanatory variable is called ''simple linear regression''; for more than one, the process is called multiple linear regression. This term is distinct from multivariate linear regression, where multiple correlated dependent variables are predicted, rather than a single scalar variable. In linear regression, the relationships are modeled using linear predictor functions whose unknown model parameters are estimated from the data. Such models are called linear models. Most commonly, the conditional mean of the response given the values of the explanatory variables (or predictors) is assumed to be an affine function of those values; less commonly, the conditional median or some other quantile is used. Like all forms of regression analysis, linear regression focuses on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georg Elias Müller
Georg Elias Müller (20 July 185023 December 1934) was a significant early German experimental psychologist who is credited with the theory of retroactive interference. Biography Early life Georg Elias Müller was born in Grimma, Saxony on 20 July 1850 to August Friedrich Müller and Rosalie Zehme Müller. His father was a theologian and professor of religion at a nearby royal academy. His family was deeply involved in a revivalist orthodoxy (Neuluthertum) that he eventually broke away from. As a child he attended the Gymnasium at Leipzig. Professional biography At 18 he attended Leipzig University where he studied history and philosophy, while there he was inducted into Herbartian Philosophy. He was always seen as studious and had an interest in Mysticism that he fulfilled by reading Goethe, Byron, and Shelley. Müller had difficulty deciding between history or philosophy, in order to make his decision he took two years off from Leipzig. During those two years, starting in 187 ...

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame". History Felix Klein and Georg Cantor are credited with putting forward the idea of an international congress of mathematicians in the 1890s.A.
