The standard deviation is one of the measures of dispersion and is defined as the square root of the variance. So by definition, the standard deviation and variance cannot take negative values. To calculate the standard deviation and variance, the mean value is used in the formula....
After accounting for individual demographic characteristics, one of the strongest predictors of adolescent birth within the population was village-level collective norms about the acceptability of adolescent childbearing, based on aggregating normative measures from the entire population. The proportion of ...
38 proposed an operational framework in which the FD within communities (FDcom) is compared to the corresponding FD for a given species pool (FDpool)38, where both measures are standardized by the number of the species in the community. FDpool includes the set of species that could potentiall...
1: the edge of the installation position bad. Elimination method: the edge of the position of the correction, should be combined with the upper axis, with the interval check. The right side of the high and low position, the general plain fabric when the bending shaft in front of the hear...
(one per species for each subsample).aBoth alpha-diversity measures were found to be significant.bSome principal component (PC) analysis PCs were significantly explained by diet (asterisk denotes Adj.p < 0.05). The percentage of variance explained for each unweighted Unifrac PC is 18.1, ...
The measures of the BPP features were discretized with the WEKA software, while the algorithmic performance measures were discretized taking into account what was considered to be a good, regular, or poor performance of the algorithms. For the values of the BPP features, we used the unsupervised...
For example, among others, Nerlove (1967) on a survey found that changes in period or concept may generate the different values of the ES. Comparing ES estimates from six alternative functional forms, five different measures of the rental price of capital, and two estimation techniques, Berndt ...
comparing non-compliant patients with compliant patients with other-setting colonoscopy. The Skewness and Kurtosis test examined the normal distribution of quantitative variables, from which the choice of the mean or median and related measures of dispersion, such as standard deviation (SD) or interqua...
