Quick Parameter Estimator (QPE)

The Quick Parameter Estimator (QPE) allows you to estimate the parameters of a distribution based on information you have about the reliability of a product, the probability of an event occurring or the typical duration of a task. You can open the QPE from the Model window or the Model Wizard by clicking the QPE icon.

The QPE includes a Wizard view and an Expert view, described below. You can toggle between the different views by clicking the Use Expert or Use Wizard button at the bottom-left corner of the window.

The Wizard view automatically selects a distribution and estimates that distribution's parameters based on your responses to a series of questions. The first page of the Wizard view asks you to choose among three different types of models that you can build with the QPE. Subsequent pages will ask more specific questions related to your selected model.
The Expert view allows you to estimate the parameters of a distribution using either two unreliability values at specified times or one unreliability value and the other parameter(s) of the distribution. Unlike the Wizard view, you must select a distribution to solve the parameter(s) for.

What's Changed? In previous versions of RCM++, the Expert view of the Quick Parameter Estimator was known as the Parameter Experimenter.
