| Abstract: | We consider the calculation of accumulated value of some annuities over a period of years in which the rate of interest is a random variable under some restrictions and aim at the expected value and variance of the accumulated value. In this paper, some special patterns of annuity changes whose payments are of the flatheaded rainbow, the rainbow, the reverse flatheaded rainbow and of the reverse rainbow, and formulas for the expected value and variance of the accumulated value are given. |
| Keywords: | random rates of interest rainbow flatheaded annuities accumulated value |
