It is of interest to know what the covariance of sample mean and sample variance is without the assumption of normality. In this article we study such a problem. We show a simple derivation of the ...

Estimation of the variance of the sample median based on small samples is discussed, and short tables are provided to facilitate calculation of the estimates.

Clinical researchers, with or without a statistical background, will find this book an invaluable aid in understanding the statistical methods cited most frequently in clinical protocols, statistical ...
