DIMORA: DIMORA Package

In federicozanghi/DIMORA: Diffusion Models R Analysis

Description

In the following package some innovation diffusion models have been implemented to analyze nonlinear growth processes, for both univariate and bivariate time series data.

The implemented models are: standard Bass model, Generalized Bass model (with rectangular shock, exponential shock, mixed shock and harmonic shock, 1 to 3 shocks available), Dynamic market potential model, and UCRCD model.

The Bass model, BM, (Bass, 1969), consists of a simple differential equation that describes the process of how new products get adopted in a population, while the Generalized Bass model, GBM, (Bass et al., 1994) is a generalization of the Bass model with a function x(t), capturing the changing speed of diffusion. In some real processes the market potential may be not constant over time and a dynamic market potential model is needed. The Guseo-Guidolin model, GGM, (Guseo and Guidolin, 2009) is a specification of this situation.

The UCRCD model, (Guseo and Mortarino, 2014) is a diffusion model useful to capture the dynamics of competition between two products within the same market. See the full documentation for more details.
