A one-factor ANOVA, with academic major as the between-subject factor, and the residual scores as the depend- ent variable, was significant based on a permutation test, [F(18, 598) = 5.09, p < 0.001,
The sales conditions also determine when a future cash inflow is verifiable and so included in earnings (along with associated cash outflows). We assume sales for period t, St, follow a random walk process:(1)St=St−1+εt,where εt is a random variable with variance σ2 and cov (...
Van Tassel (2020) documents static arbitrage opportunities between VIX futures and SPX options as VIX futures violate their lower and upper bounds implied by SPX options. Barras and Malkhozov (2016) find deviations in the variance risk premium (VRP) derived from equity prices and SPX option ...
Assuming these two sources of variance are uncorrelated so that their variances add, then alogZis about 2-15% lower than the total uncertainty of pre- dicted ground motions, the former percentage corresponding to well-sampled parts of the M-D space and the latter to poorly sampled parts. ...
Summarized data are shown as mean ± standard deviation or as frequencies (%). One-way analysis of variance (one-way ANOVA) was used to compare the mean differences and the Pearson’s chi-square test was used to compare the proportional differences in demographic characteristics and serum ...
The same procedure was applied during summer, winter, spring, autumn and the oil obtained from the four seasons was analyzed by GC–MS. The comparison was established between oil compositions of 4 seasons. The season with the highest percentage of citronellol and the yield of oil was selected ...
The purpose of this study was to address the following three research gaps. First, arguably, the relationship between human mobility and COVID-19 spread can hold in both directions: mobility can affect the spread and the spread can also influence the mobility in reverse. To the best of our ...
as tillage and organic matter (OM) addition; ii) to understand the direct and indirect relationships between soil suppressiveness and labile organic carbon fractions; and iii) to understand the relationship between soil suppressiveness and other chemical, physical and biological soil quality indicators....
This highlights the need for further studies to investigate the variance of bone tissue architecture, bone density and the macro-mechanical properties of bone, with the various parameters (BMD, strength, stiffness, toughness, microarchitecture, etc.) analysed either as separate characteristics and with...
