The purpose of this study was to examine reliability and validity of a new method of measuring hand size in which a tape measure is wrapped around the hand in a figure-of-eight pattern. In the first experiment, two testers measured hand size in 60 individuals with no recent history of injury or surgery. Intraclass correlation coefficients of 0.99 and 0.97 indicated high intratester and intertes...

the aim of this study was to assess the relative efficiency of the iranian forest management plans using the non-parametric method – data envelopment analysis (dea) as a well-known and robust technique for measuring the relative efficiency of organizations. the relative efficiency of forest management plans was calculated using the most frequency dea models such as global technical efficiency (...

We propose a simple method to assess the number of subpopulations in multivariate data by projecting the data on its principal curve and then applying Silverman’s bandwidth test to the resulting univariate sample. Our results indicate that this method works well even in high-dimensional settings with relatively small sample sizes, provided that the number of subpopulations is not large compared...
