Resampling (statistics) In statistics, resampling is the creation of new samples based on one observed sample. Resampling methods are: Permutation tests (also re-randomization tests) Bootstrapping. Cross validation. Jackknife.
A tin-based perovskite solar cell is a special type of perovskite solar cell, based on a tin perovskite structure (ASnX 3, where 'A' is a 1+ cation and 'X' is a monovalent halogen anion ). As a technology, tin-based perovskite solar cells are still in the research phase, and are even less-studied than their counterpart, lead-based perovskite solar cells. The main advantages of tin-based ...
A medical device company has agreed to pay $42 million and plead guilty to resolve U.S. charges that it concealed a malfunction in its lead-testing devices that resulted in thousands of children ...
The PDF of the paper. " Why Most Published Research Findings Are False " is a 2005 essay written by John Ioannidis, a professor at the Stanford School of Medicine, and published in PLOS Medicine. [1] It is considered foundational to the field of metascience . In the paper, Ioannidis argued that a large number, if not the majority, of published ...
Study heterogeneity. In statistics, (between-) study heterogeneity is a phenomenon that commonly occurs when attempting to undertake a meta-analysis. In a simplistic scenario, studies whose results are to be combined in the meta-analysis would all be undertaken in the same way and to the same experimental protocols.
Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method. For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated. There are different ...
This article appears in the Jun/July 2024 issue of Fortune with the headline "How Waymo steered to the front of the pack and made self-driving taxis a reality." This story was originally featured ...
Light soaking refers to the change in power output of solar cells which can be measured after illumination. This can either be an increase or decrease, depending on the type of solar cell. The cause of this effect and the consequences on efficiency varies per type of solar cell. Light soaking can generally cause either metastable electrical or structural effects. Electrical effects can vary ...
