WebTo better understand the Gompertz equation, we will do, now, an analysis more detailed of it, aiming to find its extremes values and classify, in case it exists, its equilibrium solution. … WebApr 6, 2006 · Three critical points (and the respective stages of tumour growth) can be identified on the Gompertz curve. Until it reaches 7.3% of the maximum volume the tumour grows slowly. When the tumour reaches 37% of its limit, the rate of growth is a maximum. After reaching 68%, the growth slows down (Demidenko , page 301).
