Abstract The popularity of modern portfolio theory has decreased among practitioners because its unfavorable out-of-sample performance. Estimation risk tends to affect the optimal weight calculation noticeably, especially when a large number assets are considered. To overcome these issues, many methods have been proposed in recent years, but only few address practically relevant questions relat...

in descriptive statistics, there are two computational algorithms for determining the variance s2, of a set of observations : algorithm 1: s2= - , algorithm 2: s2= , where . it is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. i this paper, based on total effect of rounding error, we prove that the second algorithm is better than ...

    In order to investigation of genotype - environment interaction is essential for selecting compatible and stable genotypes in plant breeding. For this order analysis of genotype × environment interaction and identify barley stable genotypes for warm and humid regions, this study conducted in a randomized complete block design with 4 replications and 16 genotypes with two check cultivars in ...

In order to find the high-yielding and adaptable cultivars in different environments, eight cotton genotypes including two early maturity hybrids were studied and compared with the Varamin cultivar as control in a randomized complete block design with four replications in six regions in 1997 and 1998. Using Barttlet test, some of the environments were eliminated from statistical analysis. There...
