Saturation is mentioned in many qualitative research reports without any explanation of what it means and how it occurred. Recognizing the saturation point presents a challenge ...
Many economic researchers have attempted to measure the effect of aggregate market or public policy variables on micro units by merging aggregate data with micro observations by...

Researchers typically analyze time-series-cross-section data with a binary dependent \nvariable (BTSCS) using ordinary logit or probit. However, BTSCS observations are \...
In this prospective meta-analysis of clinical trials of critically ill patients with COVID-19, administration of systemic corticosteroids, compared with usual care or placebo, w...
We extend the jackknife and the bootstrap method of estimating standard errors to the case where the observations form a general stationary sequence. We do not attempt a reducti...
The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observatio...
The conversion of an epithelial cell to a mesenchymal cell is critical to metazoan embryogenesis and a defining structural feature of organ development. Current interest in this...
