Implementation in Loglet Lab

The Loglet Lab software condenses the logistic substitution model into two steps. First, it Fisher-Pry transforms all of the data to assist in the identification of the growth (and decline) phases. Second, it asks you to give either a time window for the growth (or decline) phase or a set of parameters for each technology. Using this input, the logistic substitution engine fits a curve to the growth (or decline) phase of each technology, determines the saturation point based on the criterion in equation (9), and plots the substitution curves.

Loglet Lab can accommodate an arbitrary amount of data sets, so users can easily add one or more hypothetical competitors and envision several different scenarios for the emerging markets.
