Short description of the situations when you might use this model.
Sometimes, reliability growth data with an S-shaped trend cannot be described accurately by the Standard Gompertz or Logistic curves. Because these two models have fixed values of reliability at the inflection points, only a few reliability growth data sets following an S-shaped reliability growth curve can be fitted to them. A modification of the Gompertz curve, the Modified Gompertz model, which overcomes this shortcoming can be used instead.

Modified Gompertz Model

Sometimes, reliability growth data with an S-shaped trend cannot be described accurately by the Standard Gompertz or Logistic curves. Because these two models have fixed values of reliability at the inflection points, only a few reliability growth data sets following an S-shaped reliability growth curve can be fitted to them. A modification of the Gompertz curve, the Modified Gompertz model, which overcomes this shortcoming can be used instead.
