MAGIC Criteria
The MAGIC criteria are a set of guidelines put forth by Robert Abelson in his book ''Statistics as Principled Argument''. In this book he posits that the goal of statistical analysis should be to make compelling claims about the world and he presents the MAGIC criteria as a way to do that. What are the MAGIC criteria? MAGIC is a backronym A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The ... for: # Magnitude – How big is the effect? Large effects are more compelling than small ones. # Articulation – How specific is it? Precise statements are more compelling than imprecise ones. # Generality – How generally does it apply? More general effects are more compelling than less general ones. Claims that would interest a more general audience are more compelling. # Interestingness – ...

Robert Abelson
Robert Paul Abelson (September 12, 1928 – July 13, 2005) was a Yale University psychologist and Political science, political scientist with special interests in statistics and logic. Biography He was born in New York City and attended the Bronx High School of Science. He did his undergraduate work at MIT and his Ph.D. in psychology at Princeton University's Princeton University Department of Psychology, Department of Psychology under John Tukey and Silvan Tomkins. From Princeton, Abelson went to Yale, where he stayed for the subsequent five decades of his career. Arriving during the ''Yale Communication Project'', Abelson contributed to the foundation of attitudes studies as co-author of ''Attitude Organization and Change: An Analysis of Consistency Among Attitude Component'', (1960, with Rosenberg, Hovland, McGuire, & Brehm). While at Yale, Abelson was briefly a bass in the Yale Russian Chorus. With Milton J. Rosenberg, he developed the notion of “symbolic psycho-logic," an e ...

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. An acronym is a word derived from the initial letters of the words of a phrase, such as ''radar'' from "''ra''dio ''d''etection ''a''nd ''r''anging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin." Many fictional espionage organizations are backronyms, such as SPECTRE (''sp''ecial ''e''xecutive for ''c''ounterintelligence, ''t''errorism, ''r''evenge and ''e''xtortion) from the James Bond franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl who was abducted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structural Equation Modelling
Structural equation modeling (SEM) is a label for a diverse set of methods used by scientists in both experimental and observational research across the sciences, business, and other fields. It is used most in the social and behavioral sciences. A definition of SEM is difficult without reference to highly technical language, but a good starting place is the name itself. SEM involves the construction of a ''model'', to represent how various aspects of an observable or theoretical phenomenon are thought to be causally structurally related to one another. The ''structural'' aspect of the model implies theoretical associations between variables that represent the phenomenon under investigation. The postulated causal structuring is often depicted with arrows representing causal connections between variables (as in Figures 1 and 2) but these causal connections can be equivalently represented as equations. The causal structures imply that specific patterns of connections should appe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
