Multivariate control chats are generally used in situations where the simultaneous monitoring or control of two or more related quality characteristics is necessary. In most processes in the real world, distribution of the process characteristics are unknown or at least non-normal, so the non-parametric or distribution-free charts are desirable. Most non-parametric statistical process-control t...

In this paper, we propose a new method for checking randomness of non-Gaussian stable data based on a characterization result. This method is more sensitive with respect to non-random data compared to the well-known non-parametric randomness tests.

Organizational citizenship behavior has always been tested in the knowledge-intensive sectors of societies. Organizational citizenship behavior is a voluntary and discretionary behavior that is supposed to build up the cultural aspect of the organization; it is not part of the personnel's contractual tasks and can contribute to the successful implementation of the organization's objectives. The...

In this work, we get focused on the use of statistical techniques for behavior analysis of Artificial Neural Networks in the task of classification. A study of the non-parametric tests use is presented, using some well-known models of neural networks. The results show the need of using non-parametric statistic, because the Artificial Neural Networks used do not verify the hypothesis required fo...

a lot of people think that the economic development of a country is associated with its grossdomestic product (gdp), but gdp does not consider aspects as important as the environmental performanceof a country. nowadays, environmental issues are one of the most important aspects of the long termdevelopment of a country and play an important role in a nation’s wealth. although the analysis of cou...
