A mathematical model utilizing the geometric distribution for analyzing time-to-response data is described. This model takes into account concomitant information by means of a multivariate logistic ...
A variable undergoing logistic growth initially grows exponentially. After some time, the rate of growth decreases and the function levels off, forming a sigmoid, or s-shaped curve. For example, an ...
In several investigations, empirically observed tumor growth kinetics were well described by logistic or Gompertz models. 30 - 36 Previous mathematical frameworks for investigating tumor progression ...
