A case study is an in-depth, detailed examination of a particular case (or cases) within a real-world context. [1] [2] For example, case studies in medicine may focus on an individual patient or ailment; case studies in business might cover a particular firm's strategy or a broader market; similarly, case studies in politics can range from a narrow happening over time like the operations of a ...
The reason for this is that, unlike cross-sectional studies, in which different individuals with the same characteristics are compared, [2] longitudinal studies track the same people, and so the differences observed in those people are less likely to be the result of cultural differences across generations, that is, the cohort effect ...
The notation convention chosen here (with W 0 and W −1) follows the canonical reference on the Lambert W function by Corless, Gonnet, Hare, Jeffrey and Knuth. [3]The name "product logarithm" can be understood as follows: since the inverse function of f(w) = e w is termed the logarithm, it makes sense to call the inverse "function" of the product we w the "product logarithm".
Learning and Individual Differences (ISSN 1041-6080) is a quarterly peer-reviewed academic journal published by Elsevier dealing with individual differences within an educational context. It was established in 1989 with H. Lee Swanson as its founding editor. [1] The current (as at March 2024) editor-in-chief is Samuel Greiff, (University of ...
In machine learning and pattern recognition, a feature is an individual measurable property or characteristic of a data set. [1] Choosing informative, discriminating, and independent features is crucial to produce effective algorithms for pattern recognition, classification, and regression tasks.
There are many ways to classify research designs. Nonetheless, the list below offers a number of useful distinctions between possible research designs. A research design is an arrangement of conditions or collection. [5] Descriptive (e.g., case-study, naturalistic observation, survey) Correlational (e.g., case-control study, observational study)
Havasupai Tribe of Havasupai Reservation v. Arizona Board of Regents was brought to court on April 20, 2010. It was discovered that the DNA samples extracted from the Havasupai tribe members that were initially intended to go towards research regarding the genetic linkage to type 2 diabetes in the 1990s, were being used for additional studies.

In other words, the sequence is obtained from the sequence of monomials 1, x, x 2, … by the Gram–Schmidt process with respect to this inner product. Usually the sequence is required to be orthonormal , namely, P n , P n = 1 , {\displaystyle \langle P_{n},P_{n}\rangle =1,} however, other normalisations are sometimes used.
