  2. Accumulation function - Wikipedia

    en.wikipedia.org/wiki/Accumulation_function

    The accumulation function a(t) is a function defined in terms of time t expressing the ratio of the value at time t (future value) and the initial investment (present value). It is used in interest theory. Thus a(0)=1 and the value at time t is given by: = ().

    Cumulative distribution function for the exponential distribution Cumulative distribution function for the normal distribution. In probability theory and statistics, the cumulative distribution function (CDF) of a real-valued random variable, or just distribution function of , evaluated at , is the probability that will take a value less than or equal to .

  4. Cumulative density function - Wikipedia

    en.wikipedia.org/wiki/Cumulative_density_function

    Cumulative density function is a self-contradictory phrase resulting from confusion between: probability density function, and; cumulative distribution function.

    where F X (x) is the cumulative distribution function of the continuous age-at-death random variable, X. As Δx tends to zero, so does this probability in the continuous case. The approximate force of mortality is this probability divided by Δx. If we let Δx tend to zero, we get the function for force of mortality, denoted as μ(x):
