Assume that we are given a set of N rankings, a.k.a linear orderings on n objects. For instance, the rankings represent the individual preferences of a panel of N judges, each presented with the same set of n candidate objects. The problem of rank aggregation or of finding a consensus ranking, is formulated as finding a single ranking π0 that best agrees with all the N rankings. Kendall’s corre...

Drinking under the Influence (DUI) remains to be a public health issue as there has still been significant number of traffic deaths and injuries due DUI. Despite laws enacted impacts DUI highly publicized, high percentage people perceiving major personal safety threat furthers need review status DUIs in this country. There are various agencies country that gathered data one way or other. Howeve...

We consider random permutations which are spherically symmetric with respect to a metric on the symmetric group Sn and are consistent as n varies. The extreme infinitely spherically symmetric permutation-valued processes are identified for the Hamming, Kendall-tau and Caley metrics. The proofs in all three cases are based on a unified approach through stochastic monotonicity. MSC:

Kendall shape spaces are a widely used framework for the statistical analysis of data arising from many domains, often requiring parallel transport as tool to normalise time series or gradient in optimisation procedures. We present an implementation pole ladder, algorithm compute based on geodesic parallelograms and compare it methods by integration ordinary differential equation.

background: we aimed to assess the high-risk group for suicide using different classification methods includinglogistic regression (lr), decision tree (dt), artificial neural network (ann), and support vector machine (svm). methods: we used the dataset of a study conducted to predict risk factors of completed suicide in hamadan province, the west of iran, in 2010. to evaluate the high-risk grou...

background: the workers who are working in the open and warm environments are at risk of health effects of climate and heat changes. it is expected that the risk is increase with global warming. this study aimed to investigate the changes of wet bulb globe temperature (wbgt) index in the past and to predict their trend of future changes in tehran, capital of iran. methods: the meteorological da...
