High Quality Content by WIKIPEDIA articles! The shifted Gompertz distribution is the distribution of the largest order statistic of two independent random variables which are distributed exponential and Gompertz with parameters b and b and ? respectively. It has been used as a model of adoption of innovation. he shifted Gompertz distribution is right-skewed for all values of ?. It is more flexible than the Gompertz distribution (Gumbel distribution). If ? varies according to a gamma distribution with shape parameter ? and scale parameter ? (mean = ??), the cumulative distribution function is Gamma/Shifted Gompertz (G/SG). When ? is equal to one, the G/SG reduces to the Bass model.
