An up-to-date review of rural road accident statistics for Iran is presented The review considers sources of accident statistics in Iran and the means by which they are collected. The statistics are considered in relation to accident causal and risk factors. A comparison is made with statistics available for other countries at a similar stage of development and countries with highly developed e...

This is a quantitative investigation of the importance of technological change speci"c to new investment goods for postwar US aggregate #uctuations. A growth model that incorporates this form of technological change is calibrated to US data and simulated, using the relative price of new equipment to identify the process driving investmentspeci"c technology shocks. The analysis suggests that thi...

• Frequentist probability concerns the possibility of NO difference • The starting premise is a population with known features • Bayes’ theories concern modifying a pre-existing possibility • Experiments revise the previous estimate • Lab experiments do not often use random samples • Small numbers, random allocation to treatment • Well suited to permutation tests • Choose the test when you devi...

Analyses at the county level show lower mortality rates where there are more primary care physicians, but this is not the case for specialist supply. These findings confirm those of previous studies at the state and other levels. Increasing the supply of specialists will not improve the United States' position in population health relative to other industrialized countries, and it is likely to ...

Recently, a gradual increase in some chronic diseases has been observed in tandem with the aging of the population. Globally, there has been a significant increase in the importance of cancer, and according to a recent report from the International Agency for Research on Cancer, its overall impact has more than doubled in the past 30 years [1]. The burden of cancer will increase to 22 million n...

In this paper we suggest a completely nonparametric test for the assessment of similar marginals of a multivariate distribution function. This test is based on the asymptotic normality of Mallows distance between marginals. It is also shown that the n out of n bootstrap is weakly consistent, thus providing a theoretical justification to the work in Czado & Munk [12]. The test is extended to cro...

Developed countries with low fertility and mortality rates are already experiencing population aging and will continue to do so. Some developing countries undergoing demographic transitions are beginning to acknowledge the issues of population aging. The projected declines in fertility in other developing countries will mean substantial population aging in the future. Alternative measures for p...

We investigate the link between death rates and smoking prevalence in ten developed countries with the aim of using smoking prevalence data to explain differences in country-specific death rates. A particular problem in building a stochastic mortality model based on smoking prevalence is that there are in general no separate mortality data for smokers and non-smokers available. We show how we c...

Well described tools for comparing two populations via their cumulative distribution functions F and F0 are the so-called relative distribution R (t) = F { F−1 0 (t) } and the corresponding relative density (or grade density) r (t). The authors propose a kerneltype estimator for the relative density r (t) in the situation where independent samples of right-censored observations are available fr...

Bootstrapping is a famous statistical tool that involves resampling procedure to select sample from a population. In this study, we applied randomx bootstrap in binary logistic regression for published data set namely Umaru Impact data. We conducted bootstrap for the coefficient by using SAS (Statistical Analysis System). We observe the distribution of the estimated coefficients with different ...
