The New York Times of November 10, 1919, reported on Einstein's confirmed prediction of gravitation on space, called the gravitational lens effect.. The concept of predictive power, the power of a scientific theory to generate testable predictions, differs from explanatory power and descriptive power (where phenomena that are already known are retrospectively explained or described by a given ...
Explanatory power is the ability of a hypothesis or theory to explain the subject matter effectively to which it pertains. Its opposite is explanatory impotence . In the past, various criteria or measures for explanatory power have been proposed.
Over time, as successive modifications build on top of each other, theories consistently improve and greater predictive accuracy is achieved. Since each new version of a theory (or a completely new theory) must have more predictive and explanatory power than the last, scientific knowledge consistently becomes more accurate over time.
For example, explanatory power over all existing observations (criterion 3) is satisfied by no one theory at the moment. [ 10 ] Whatever might be the ultimate goals of some scientists, science, as it is currently practiced, depends on multiple overlapping descriptions of the world, each of which has a domain of applicability.
It has predictive power. A linguistic theory that aims for explanatory adequacy is concerned with the internal structure of the device [i.e. grammar]; that is, it aims to provide a principled basis, independent of any particular language, for the selection of the descriptively adequate grammar of each language. [4]
Its scope – the number and variety of phenomena which it could explain, if it is true (its "explanatory power"). its novelty or originality – the extent to which the hypothesis is a genuinely new departure from the received scientific ideas. whether it enables new and novel predictions ("predictive power").
Actual vs. expected salaries during 2018-19 season. In 2025, a world in which Dončić is much better than he was in 2018-19 and much more popular with an NBA Finals trip, I find the notion that ...
It is an inverse measure of the explanatory power of ^, and can be used in the process of cross-validation of an estimated model. Knowledge of g would be required in order to calculate the MSPE exactly; in practice, MSPE is estimated.
