The mortality of German joint stock companies is investigated using life table techniques. An EDB-distribution or Hjorth-distribution and an exponential distribution are fitted to the hazard rates, whereby the population is divided into small and large firms. Survivor functions and life...

The use of the Box-Jenkins approach for forecasting the population of the United States to the year 2080 is discussed. The forecasts are based on data for 1900-1980. It is shown that no major difference exists between the Box-Jenkins approach and parabolic trend curves when making long-range...
