  2. Formula for change - Wikipedia

    en.wikipedia.org/wiki/Formula_for_change

    The formula for change (or "the change formula") provides a model to assess the relative strengths affecting the likely success of organisational change programs. The formula was created by David Gleicher while he was working at management consultants Arthur D. Little in the early 1960s, [1] refined by Kathie Dannemiller in the 1980s, [2] and further developed by Steve Cady.

  3. Population dynamics - Wikipedia

    The algebraic symbols b, d and r stand for the rates of birth, death, and the rate of change per individual in the general population, the intrinsic rate of increase. This formula can be read as the rate of change in the population (dN/dt) is equal to births minus deaths (B − D). [2] [13] [17]

    For example, when it is 3 times as big as it is now, it will be growing 3 times as fast as it is now. In more technical language, its instantaneous rate of change (that is, the derivative) of a quantity with respect to an independent variable is proportional to the quantity itself. Often the independent variable is time.

    The rule can then be derived [2] either from the Poisson approximation to the binomial distribution, or from the formula (1−p) n for the probability of zero events in the binomial distribution. In the latter case, the edge of the confidence interval is given by Pr( X = 0) = 0.05 and hence (1− p ) n = .05 so n ln (1– p ) = ln .05 ≈ −2.996.
