Quality in Unimode and Mixed-Mode designs: A Multitrait-Multimethod approach
Survey Research Methods, 2010 So far, most surveys used face-to-face or telephone questionnaires in order to collect data. But the costs of achieving a survey using these traditional modes increase. At the same time, the response rates decrease, making the idea of switching mode very

Learning to Rank with Selection Bias in Personal Search
Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, 2016 Click-through data has proven to be a critical resource for improving search ranking quality. Though a large amount of click data can be easily collected by search engines, various biases make it difficult to fully leverage this type of data. In the past,

Molecular Oncology, EarlyView.Low expression of five purine metabolism‐related genes (ADSL, APRT, ADCY3, NME3, NME6) was correlated with poor survival in colorectal cancer. Immunohistochemistry analysis showed that low NME3 (early stage) and low ADSL/NME6 (late stage) levels were associated with high risk.

Avoiding selection bias in gravitational wave astronomy
New Journal of Physics, 2013 When searching for gravitational waves in the data from ground-based gravitational wave detectors, it is common to use a detection threshold to reduce the number of background events which are unlikely to be the signals of interest.

Response-Based Sampling for Binary Choice Models With Sample Selection
Econometrics, 2018 Sample selection models attempt to correct for non-randomly selected data in a two-model hierarchy where, on the first level, a binary selection equation determines whether a particular observation will be available for the second level (outcome equation)

Molecular Oncology, EarlyView.This article advocates integrating temporal dynamics into cancer research. Rather than relying on static snapshots, researchers should increasingly consider adopting dynamic methods—such as live imaging, temporal omics, and liquid biopsies—to track how tumors evolve over time.

Shift work and cardiovascular disease – do the new studies add to our knowledge?
Scandinavian Journal of Work, Environment & Health, 2018 The association of shift work with cardiovascular disease (CVD) has been studied for decades with new systematic reviews repeatedly being published (1–4). Based on 34 studies and over 2 million employees, the systematic review of Vyas et al (4) concluded

Selection Bias Due to Loss to Follow Up in Cohort Studies.
Epidemiology, 2016 Selection bias due to loss to follow up represents a threat to the internal validity of estimates derived from cohort studies. Over the past 15 years, stratification-based techniques as well as methods such as inverse probability-of-censoring weighted ...
