nowadays, innovation is one of the most important factors for a business to survive. due to rapid changes and short life cycle of technology in information and communication technology (ict) companies, considerable attention is given to innovation. this study aims to identify and rank the impact factors on open innovation success in ict firms. this practical research is quantitative and uses th...

global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...

Analyzing monitoring data efficiently is a classic problem in structural health monitoring. A nonparametric test method, the Mann–Kendall (MK) was implemented this study, which commonly used to detect monotonic trends series of environmental data. Using MK three types time were studied: stress measured concrete prism compression test, resultant force obtained from pseudostatic reinforced masonr...

Glossary Hypothesis A hypothesis is a statement concerning the (joint) distribution underlying the observed data. Nonparametric test In contrast to a parametric test, a nonparametric test does not presume a particular parametric structure concerning the data generating process. Serial dependence Statistical dependence among time series observations.

The literature on statistical test of stochastic dominance has thus far been concerned with univariate distributions. This paper presents nonparametric statistical tests for multivariate distributions. This allows a nonparametric treatment of multiple welfare indicators. These test are applied to a time series of cross-section datasets on household level total expenditure and non labour market ...

thunderstorms are climatical phenomena, which sometimes can cause irreparable damage to the ecology. in this study to identify any trends in the frequency of days with thunderstorms in iran, long-term statistics of 33 synoptic stations, from the beginning until 2005 was used. at first by applying nonparametric man-kendall and sen’s estimator methods on four seasonal time series, and one annua...

Hydrological drought is defined by long-term decrease in levels and flows of water bodies. The task of this paper is to analyze and identify statistical trends of low flows in streams in the eastern Slovakia. Methodology for evaluating hydrological drought is based on statistical analysis of observed low stream flows at chosen river stations – annual and seasonal. Mann-Kendall statistical test ...
