Relative growth rate (RGR) is growth rate relative to size - that is, a rate of growth per unit time, as a proportion of its size at that moment in time. It is also called the exponential growth rate, or the continuous growth rate.
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. RGR is the relative growth rate. RGR can then be written as:
The equivalent concept to doubling time for a material undergoing a constant negative relative growth rate or exponential decay is the half-life. The equivalent concept in base- e is e -folding . Graphs comparing doubling times and half lives of exponential growths (bold lines) and decay (faint lines), and their 70/ t and 72/ t approximations.
To use the matrix, analysts plot a scatter graph to rank the business units (or products) on the basis of their relative market shares and growth rates. This results is a chart showing: Cash cows, where a company has high market share in a slow-growing industry. These units typically generate cash in excess of the amount of cash needed to ...
For any fixed b not equal to 1 (e.g. e or 2), the growth rate is given by the non-zero time τ. For any non-zero time τ the growth rate is given by the dimensionless positive number b. Thus the law of exponential growth can be written in different but mathematically equivalent forms, by using a different base.
Both SLA and LMA are frequently used in plant ecology and biology. SLA is one of the components in plant growth analysis, and mathematically scales positively and linearly with the relative growth rate of a plant. LMA mathematically scales positively with the investments plants make per unit leaf area (amount of protein and cell wall; cell ...
Data source: Yahoo Finance. YOY = year over year. 3. A bargain valuation. I sense that the sell-off in Dollar General's stock is overdone, leaving shares fundamentally undervalued trading at 14 ...
Understanding the differences between the R* theory and its major alternative the CSR triangle theory is a major goal in community ecology for many years. [6] [7] Unlike the R* theory, the CSR theory predicts that competitive ability is determined by relative growth rate and other size related traits.
