Copulas and Vines (stat08012)
Copulas and vines allow us to model the distribution of multivariate random variables in a flexible way. This article introduces copulas via Sklar’s theorem, explains how pair copula constructions are built by decomposing multivariate copula densities and illustrates vine graphical representations.
متن کاملEnsiling of Potato Vines
Potato vines are a potential feed for cattle if the vines can be preserved. The objectives of this study were primarily to study alternative methods to preserve potato vines by ensiling and determine the effects of soil contamination on ensiling. In experiment 1, vines from four potato varieties were harvested individually with a flail chopper set at three heights to vary soil contamination. Th...
متن کاملArrangement and density of junctional feet in crayfish muscle fibres.
Junctional feet in tubulo-reticular junctions of crayfish muscle fibres are arranged tetragonally with a centre-to-centre spacing of 30-34 nm. The resulting density of 860-1110 feet per 1 micron 2 of the junctional membrane is similar to that reported for other animal species. Using data of a previous stereological study, there are 150-190 feet per 1 micron 2 of the total T-tubule surface and 6...
متن کاملScience amongst the vines
Introduction classically, cell signalling has been viewed in terms of linear pathways that lead from external or internal stimuli to cellular effectors. But this simple view developed more as a means to visualize and to understand the individual components of these complex systems, rather than to reflect reality. it is now clear that, in most cases, cell signalling is much more complex and invo...
متن کاملeffect of planting date, plant density and planting arrangement of rice yield
an experiment was conducted as a split – split plot in form of a randomized block design with four replications in cilakhor region of iran in 2004. the main factor was the seed planting date with three levels (5, 12 and 25 april), sub factor was the crop density with two levels (160,000 and 250,000 pl/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidista...
