“…For example, the theoretical grounding for the traditional 'modified exponential model' lies in an assumption that the temporal path of technology diffusion is made possible by the spread of information from a central source. A variant of the modified exponential model is the logistic model used by Karshenas and Stoneman (1993), Rogers (1995), Geroski (2000), Scitovski and Meler (2002), in which the authors modified the central information source theory by including the input of previous users so that a secondary information source, namely 'word-of-mouth', is incorporated into the model. Using the logistic function of the epidemic model, we attempt to identify the precise patterns of mobile telecommunications.…”

“…The diffusion of mobile services in this equation follows an S-shaped curve. Rogers (1995) and Scitovski and Meler (2002) demonstrated the analysis of the impact of the relative magnitude of the diffusion parameter a and b on the pattern of diffusion.…”

“…These data, taken from , have been used extensively in the diffusion modeling literature to illustrate the efficiency of estimation procedures (see Schmittlein and Mahajan, 1982;Scitovski and Meler, 2002;Srinivasan and Mason, 1986).…”

“…There are several other methods which can be used to estimate the unknown parameters in new product diffusion models (see, e.g., Scitovski and Meler, 2002). A very popular technique for parameter estimation is the least squares method.…”

“…Se utilizan los modelos de difusión porque los modelos clásicos de previsión se basan en la extrapolación de los datos de las ventas históricas del producto, pero cuando no existen datos históricos las técnicas tradicionales de previsión no son aplicables (Morrison, 1995). Los modelos de difusión, ampliamente utilizados en marketing (Meade e Islam, 2006), tienen el propósito de estimar las ventas de los productos nuevos antes del lanzamiento real de los mismos (Scitovski y Meler, 2002) cuando no existe información histórica de los mismos sino de patrones de comportamiento de productos similares. El modelo de difusión utilizado en nuestro caso es el propuesto por Bass (1969), el cual asume que las adopciones de los consumidores no sólo dependen de la influencia interna generada por la presión social (de los pioneros que adoptan primero el producto) sino también por influencias externas, como lo es la publicidad.…”
