It is a sigmoid function which describes growth as being slowest at the start and end of a given time period. The right-side or future value asymptote of the function is approached much more gradually by the curve than the left-side or lower valued asymptote. This is in contrast to the simple logistic function in which both asymptotes are appro… chittagong education board resultWebBroadly, the macroscopic growth models described below can be binned into three categories: (i) exponential, (ii) sigmoidal, and (iii) power law models.
