Actuaries and demographers have a long tradition of using collateral data to improve mortality estimates. Three main approaches have been used to accomplish the improvement — mortality laws, model life tables, and relational methods. The present paper introduces a regression model that incorporates all of the beneficial principles from each of these approaches. The model is demonstrated on mort...

Consider the SVD X = UDV >, where U is n× n, V is p× p and D is an n× p “diagonal” matrix with entries d1 < . . . < dn. Define two groups of left and right singular vectors associated with the q smallest and n − q largest singular values. Let the groups be defined by Uq, Un−q and Vq, Vn−q . Suppose HJ chooses as its row-basis the n−q largest right singular vectors, Vn−q . Then, from Table 1 of ...

In 1992, I wrote an article on a method of modifying the Decennial US Life Table to accommodate any pattern of excess mortality expressed in terms of excess death rate (EDR), for the specific purpose of calculating the reduced life expectancy, e. I believe this was the first article published in the Journal of Insurance Medicine (JIM) that dealt specifically with life expectancy as an index of ...

today, health-related quality of life (hrqol) is an important indicator of development; however, due to the greater vulnerability, hrqol level of women is lower than men, especially in rural regions. this problem has doubled the necessity to investigate and identify the factors affecting hrqol. given the importance of the issue, the purpose of this descriptive- correlative research was to study...

The main objective of this study is to analyze spillover fluctuations between inflation fluctuation and (un)employment fluctuation in relation to agriculture, industry and services sectors of Iran. In line with this, PANEL in Mean-MGARCH model has been used concerning Iran’s agriculture, industry and services sectors over the period of time from spring 2002 to winter 2016. The results show that...

Knowledge of the nutrient content of foods is fundamental for virtually all nutrition-related projects, programmes and policies. Low quality compositional data may lead to inappropriate policies and funds spent unnecessarily. Existing food composition tables (FCT) for most West African countries date back to 1960 and 1970 and contain in general few foods and components without documentation. As...
