Comment: Understanding OR, PS and DR
We congratulate Kang and Schafer (KS) on their excellent article comparing various estimators of a population mean in the presence of missing data, and thank the Editor for organizing the discussion. In this communication, we systematically examine the propensity score (PS) and the outcome regression (OR) approaches and doubly robust (DR) estimation, which are all discussed by KS. The aim is to...
متن کاملYoshioka and co - workers
Sir, The paper by Yoshioka et al. (Archives, 1978, 53, 334), gives a guide to gentamicin dosage for an age group missed by the popular adult nomograms. Such a guide is necessary when choosing initial dosage, but we believe that subsequent maintenance therapy should be monitored by determining serum gentamicin levels in all patients rather than just in 'difficult' cases as suggested by the autho...
متن کاملIdentification of the Bray-Curtis similarity index: Comment on Yoshioka (2008)
In a recent As I See It, Yoshioka (2008, Mar Ecol Prog Ser 368:309–310) stated that the term Bray-Curtis should only be used for doubly-standardised data, and when data counts are used to calculate similarity, the term Czekanowski is correct; by using the wrong name, it is claimed, marine ecologists demonstrate a lack of knowledge and introduce confusion. This needs to be rectified. It is incor...
متن کاملComment on the comment by Dr. Marino and Dr. Frilot on "Proposed test for detection of nonlinear response in biological preparations exposed to RF energy".
In their Comment on the paper of Balzano [2002] on the detection of nonlinear responses, Marino and Frilot [2003] state that certain possible biological systems with a response described by ‘‘non linear differential equations’’ can respond (chaotically) to an interaction that is ‘‘arbitrarily small, say kT/10.’’ This is correct but does not lead to the conclusion that significant biological eff...
