Using two sets of data, including daily prices (open, close, high and low) of all S&P 500 stocks between 1992 and 1996, we perform a satistical test of the predictive capability of candlestick patterns. Out-of-sample tests indicate statistical signiŽcance at the level of 36 standard deviations from the null hypothesis, and indicate a proŽt of almost 1% during a two-day holding period. An essent...

Nowadays, one of the most important topics in risk management of banks, financial, and credit institutions is credit risk management. In this research, the researchers used survival analytic methods for credit risk modeling in terms of the conditional distribution function of default time. As a practical task, the authors considered the reward credit portfolio of Tose'e Ta'avon Bank of Guilan P...

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...

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with diff...

Scholz and Stephens (1987, Journal of the American Statistical Association 82, 918-924) proposed a nonparametric k-sample Anderson-Darling statistic for grouped data. This note demonstrates that a partition-of-chi 2 method may give a more powerful nonparametric test, particularly when alternatives other than location shift are important. A taste-test example provides motivation.
