Categorized underEconomicsFinanceMathematics & Statistics Exponential Growth vs Logistic Growth The difference between exponential growth and logistic growth can be seen in terms of the growth of population.Population growth is defined as an increase in the size of a population over a specific time period.The growth rate is calculated using two factors the number ofpeople and […]

, named afterBenjamin Gompertz, is asigmoid function. It is a type ofmathematical modelfor atime series, where growth is slowest at the start and end of a time period. The right-hand or future valueasymptoteof the function is approached much more gradually by the curve than the left-hand or lower valued asymptote, in contrast to thesimple logistic […]

calculates simple metrics to summarize growth curves. Growth curves are commonly used in a variety of microbial experiments, including experimental evolution. The data are typically obtained by repeatedly measuring the cell density. Modern microbial growth curves can be conducted in a plate reader and may result in hundreds of absorbance measurements over the course of […]

This lesson will introduce you to some basic concepts of population growth and allow you to experiment with them using the included Java applets The term population growth refers to how the number of individuals in a population increases (or decreases) with time. This growth is controlled by the rate at which new individuals are […]

We often assume that life works in a linear fashion. People will say,You get out of life what you put into it.The basic idea is that for each unit of effort you put into a given task, you get some unit of return. For example, if you make $25 per hour and you work for […]

Efficient design of new processes and products requires not only an effective problem solving, but reliable forecasts of coming and distant changes. Decision making about investments into emerging technologies and strategic planning activities also rely upon consistent forecasts of technological substitution. There is a long record of applying different extrapolation techniques and, in particular, the […]

The geometric or exponential growth of all populations is eventually curtailed byfoodavailability,competitionfor other resources,predation, disease, or some other ecological factor. If growth is limited by resources such as food, the exponential growth of the population begins to slow as competition for those resources increases. The growth of the population eventually slows nearly to zero as […]

If the number of people, y, who have heard a rumor is growing at a rate proportional to how many have heard it, then we get the differential equation y = ky, where y = dy/dt. In this case the growth is exponential, and the solution is y = A. The graph keeps getting higher […]
