    He applied the same mathematical formula to describe plant size over time. The equation for exponential mass growth rate in plant growth analysis is often expressed as: = ⁡ Where: M(t) is the final mass of the plant at time (t). M 0 is the initial mass of the plant.

  3. Euler–Lotka equation - Wikipedia

    en.wikipedia.org/wiki/Euler–Lotka_equation

    In the study of age-structured population growth, probably one of the most important equations is the Euler–Lotka equation.Based on the age demographic of females in the population and female births (since in many cases it is the females that are more limited in the ability to reproduce), this equation allows for an estimation of how a population is growing.

  4. Growing degree-day - Wikipedia

    en.wikipedia.org/wiki/Growing_degree-day

    Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.

  5. Time-weighted return - Wikipedia

    en.wikipedia.org/wiki/Time-weighted_return

    In general, these sub-periods will be of unequal lengths. The returns over the sub-periods between external flows are linked geometrically (compounded) together, i.e. by multiplying together the growth factors in all the sub-periods. The growth factor in each sub-period is equal to 1 plus the return over the sub-period.

    Also, the perpetuity growth rate assumes that free cash flow will continue to grow at a constant rate into perpetuity. Consider that a perpetuity growth rate exceeding the annualized growth of the S&P 500 and/or the U.S. GDP implies that the company's cash flow will outpace and eventually absorb these rather large values. Perhaps the greatest ...

    a) When the growth g is zero, the dividend is capitalized. =. b) This equation is also used to estimate the cost of capital by solving for . = +. c) which is equivalent to the formula of the Gordon Growth Model (or Yield-plus-growth Model):
