A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.
WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

Abstract Background Associations between haplotypes and quantitative traits provide valuable information about the genetic basis of complex human diseases. Haplotypes also provide an effective way to deal with untyped SNPs. Two major…
Marcelo Boareto, Nestor Caticha · 2014 · Microarrays
Microarray data analysis typically consists in identifying a list of differentially expressed genes (DEG), i.e., the genes that are differentially expressed between two experimental conditions. Variance shrinkage methods have been…

ABSTRACT Background Feedback is an essential part of the educational process as it enriches students' learning experiences, provides information about their current performance, shows them what is lacking in achieving goals, and provides…
Sarvnaz Karimi, Jie Yin, Jiri Baum · 2015 · Computational Linguistics
In recent years, many studies have been published on data collected from social media, especially microblogs such as Twitter. However, rather few of these studies have considered evaluation methodologies that take into account the…

Plant roots have been observed up to 70 m in depth – what would compel a plant to root so deeply? Earlier work shows that the climate, soil and drainage all affect rooting depth, but with conflicting results. For example, both the deepest…
Karolina Cyll, Sven Löffeler, Birgitte Carlsen et al. · 2022 · Scientific Reports
Abstract Active surveillance (AS) is standard of care for patients with low-risk prostate cancer (PCa), but its feasibility in intermediate-risk patients is controversial. We compared outcomes of low- and intermediate-risk patients managed…
Huijun Tang, Jiangbo Qian, Yangguang Liu et al. · 2022 · International Journal of Computational Intelligence Systems
Abstract Statistically significant pattern mining (SSPM) is to mine patterns with significance based on hypothesis test. Under the constraint of statistical significance, our study aims to introduce a new preference relation into high…
Ann Oakley · 2012 · Evidence & Policy
The contrasting careers of two government-sponsored commissions of inquiry in the late 1960s are the focus of this paper, which examines what can be learnt from them about the impact, or lack of impact, of such bodies on policy making. The…
Andrea Montanari, Yuchen Wu · 2024 · Information and Inference: A Journal of the IMA
Abstract We consider a class of statistical estimation problems in which we are given a random data matrix ${\boldsymbol{X}}\in{\mathbb{R}}^{n\times d}$ (and possibly some labels ${\boldsymbol{y}}\in{\mathbb{R}}^{n}$) and would like to…
