Relative growth rate index

In classical growth analysis, relative growth rate (RGR) is calculated as RGR = (ln W 2 – ln W 1 )/(t 2 – t 1 ), where W 1 and W 2 are plant dry weights at times t 1 and t 2 . Since RGR is usually calculated using destructive harvests of several individuals, an obvious approach is to substitute W 1 and W 2 with sample means 1 and 2. AGR is the simplest index to measure plant growth rate. However, it has limitations due to the fact that it can be used only to compare growth of vey similar plants (es. with the same age or Relative market share is calculated by subtracting a company's market share from 100 to find the percentage it does not control. If Company Z controls 30% of its market, this means it does not control 70%. From there, the company's market share is divided by the percentage of the market it does not control.

Relative growth rate is the slope of a curve that represents logarithmic growth over a period of time. An exponential growth rate is not sustainable over time. The curve typically flattens out, representing a saturation in growth at a certain point in time. Two of the most popular ways to measure growth are the average annual growth rate and the compound annual growth rate. In this article, we’ll compare the two and explain how to find growth rate. We’ll also go over market share and why it’s incredibly relevant when calculating the growth rate.
