consider the problem of interval estimation odds ratio. An asymptotic confidence is widely applied in economics, medicine, sociology, etc. Unfortunately, this has a poor coverage probability, significantly smaller than nominal level. In paper, new proposed. Its construction requires only information on sizes samples and sample The probability proposed at least

For the power of two-sided hypothesis testing about the mean of a normal population, we derive a 100(1 − alpha)% confidence interval. Then by using a numerical method we will find a shortest confidence interval and consider some special cases.

BACKGROUND Traumatic knee dislocations that result in multiple-ligament knee injuries are unusual and are poorly studied. We are not aware of any prospective data regarding their treatment. Both the optimum timing of surgery for repair or reconstruction and the aggressiveness of rehabilitation are debated. The purpose of this systematic review was to compare the outcomes of early, delayed, and ...

There are many real problems in which multiple responses should be optimized simultaneously by setting of process variables. One of the common approaches for optimization of multi-response problems is desirability function. In most real cases, there is a correlation structure between responses so ignoring the correlation may lead to mistake results. Hence, in this paper a robust approach based ...

This study compares temporomandibular joint dysfunction (TMD) symptoms before and after bilateral sagittal split ramus osteotomy, and identifies predictive factors for the postoperative TMD symptoms by assessing the adjusted odds ratio using multiple logistic regression analysis. A consecutive series of 37 cases treated only with bilateral sagittal split ramus osteotomy were evaluated. New post...

In nature, the mechanical properties of geological bodies are very complex, and their various mechanical parameters are vague, incomplete, imprecise, and indeterminate. However, we cannot express them by the crisp values in classical probability and statistics. In geotechnical engineering, we need to try our best to approximate exact values in indeterminate environments because determining the ...

background: despite growing interest in the public health of sexual minority, youth around the world due to the high rates of suicidal ideation and attempts in this population, few studies on the sexual orientation of korean adolescents have been conducted. therefore, this study investigated the relationship between the sexual orientation of korean adolescents and their suicide-related behavior...
