%description
The implemented methods are: Standard Bass model, Generalized Bass model
(with rectangular shock, exponential shock, and mixed shock. You can
choose to add from 1 to 3 shocks), Guseo-Guidolin model and Variable
Potential Market model, and UCRCD model. The Bass model consists of a
simple differential equation that describes the process of how new
products get adopted in a population, the Generalized Bass model is a
generalization of the Bass model in which there is a "carrier" function
x(t) that allows to change the speed of time sliding. In some real
processes the reachable potential of the resource available in a temporal
instant may appear to be not constant over time, because of this we use
Variable Potential Market model, in which the Guseo-Guidolin has a
particular specification for the market function. The UCRCD model
(Unbalanced Competition and Regime Change Diachronic) is a diffusion model
used to capture the dynamics of the competitive or collaborative
transition.
