Detecting Unusual Score Patterns in the Context of Relevant Predictors | SpringerLink

From the brilliance of Dr. Joel Schneider.  Although statistically complicated, these procedures (and other similar beauties by Dr. Schneider) could easily be implemented in test "smart" scoring software.

Neuropsychological assessment requires integrating new information with what is already known about an examinee. In constructing a case conceptualization, it can be helpful to quantify how unusual a pattern of scores is in the context of other quantitative data. This tutorial explains how two powerful statistical and psychometric concepts, conditional distributions and the Mahalanobis distance, are especially useful when used together to identify unusual score patterns after controlling for other scores. Graphical illustrations, R code, and instructions for a free and user-friendly web app are provided.

What is Green Hydrogen and why should we start using it.

What is Green Hydrogen? Hydrogen that is produced from renewable energy sources is called Green Hydrogen.It has gained much importance in the global world and it is believed that the fuel can play a major role in decarbonizing sectors of the economy   that is hard-to-electrify   like aviation, long-haul trucking and heavy manufacturing.   How is Green Hydrogen Formed?     Green Hydrogen is produced if renewable energy is used to produced electricity for the electrolysis of water. In this case, the hydrogen is produced without any harmful emission.                                               Distribution of Green Hydrogen Hydrogen can be distributed in liquefied or compressed form or through a pipeline. Compressed or liquefied distribution can be done by both land and sea. The entire value chain is green starting from the pr...

From MDPI: "Multidimensional Scaling of Cognitive Ability and Academic Achievement Scores" - Open Access….you can download and read for free!

I LOVE MDS and modern visual-graphic methods (e.g., psychometric network analysis) for analyzing multidimensional cognitive and achievement data https://www.mdpi.com/1981340 : Multidimensional Scaling of Cognitive Ability and Academic Achievement ScoresMultidimensional scaling (MDS) was used as an alternate multivariate procedure for investigating intelligence and academic achievement test score correlations. Correlation coefficients among Wechsler Intelligence Scale for Children, Fifth Edition (WISC-5) and Wechsler Individual Achievement Test, Third Edition (WIAT-III) validity sample scores and among Kaufman Assessment Battery for Children, Second Edition (KABC-II) and Kaufman Test of Educational Achievement, Second Edition (KTEA-2) co-norming sample scores were analyzed using multidimensional scaling (MDS). Three-dimensional MDS configurations were the best fit for interpretation in both datasets. Subtests were more clearly organized by CHC ability and academic domain instead of ...

 Recent developments, current challenges, and future directions in electrophysiological approaches to studying intelligence - ScienceDirect  https://ift.tt/3lH7cTd Abstract EEG studies represent an important sub-discipline in the field of intelligence research and have significant potential to advance the theoretical understanding and practical applications of the construct. This commentary reviews key themes and major developments in the field from the last several decades, and outlines open questions and future directions for the next phase of research. Two main areas of progress in recent years relate to (1) improvements in study design and psychometric approaches, and (2) increased integration with cognitive psychology and neuroscience. In turn, these advances have clarified several themes and pressing issues. These include: The need to establish the replicability and effect sizes of key effects, the need to explicitly attend to the distinction between trait- and task...
