How Robust Standard Errors Expose Methodological Problems They Do Not Fix, and What to Do About It
“Robust standard errors” are used in a vast array of scholarship to correct standard errors for model misspecification. However, when misspecification is bad enough to make classical and robust standard errors diverge, assuming that it is nevertheless not so bad as to bias everything else requires considerable optimism. And even if the optimism is warranted, settling for a misspecified model, w...
متن کاملUniversal Grammar and Chaos/Complexity Theory: Where Do They Meet And Where Do They Cross?
Abstract The present study begins by sketching "Chaos/Complexity Theory" (C/CT) and its applica-tion to the nature of language and language acquisition. Then, the theory of "Universal Grammar" (UG) is explicated with an eye to C/CT. Firstly, it is revealed that CCT may or may not be allied with a theory of language acquisition that takes UG as the initial state of language acquisition for ...
متن کاملExplorations in statistics: standard deviations and standard errors.
Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This series in Advances in Physiology Education provides an opportunity to do just that: we will investigate basic concepts in statistics using the free software package R. Because this series uses R solely as a vehicle with which to explore basic concepts in statistics, ...

متن کاملErrors in health care management: what do they cost?
BACKGROUND Iatrogenic injuries are relatively common and a potentially avoidable source of morbidity. The economic evaluation of this area has been limited by the lack of good quality national data to provide an estimate of incidence, associated disability, and preventability of iatrogenic injuries. Two recent surveys, the Quality in Australian Health Care Study (QAHCS) and the Utah Colorado St...
