Advanced statistics: Understanding Medical Record Review (MRR) Studies

Advanced statistics: understanding medical record review (MRR) studies.

Medical record review (MRR) studies have been reported to make up 25% of all scientific studies published in emergency medical (EM) journals. However, unlike other study designs, there are no standards for reporting MRRs and very little literature on the methodology for conducting them. The purpose of this article is to provide the reader with methodological guidance regarding the strengths and...

Surprisingly, this aspect seems to have been totally ignored by books on medical ethics. This paper discusses how the statistical aspects affect the ethics. The relation between biostatistics and medical research is explored. All stages of a medical research exercise are ...

Entropy Properties of Certain Record Statistics and Some Characterization Results

In this paper, the largest and the smallest observations are considered, at the time when a new record of either kind (upper or lower) occurs based on a sequence of independent random variables with identical continuous distributions. We prove that sequences of the residual or past entropy of the current records characterizes F in the family of continuous distributions. The exponential and the ...
