2-Subpopulation Mixed Weibull Example

We will illustrate mixed Weibull analysis using a set of simulated data. To repeat this example, first use the Monte Carlo utility to generate two sub-populations of data using a 2-parameter Weibull distribution. Then analyze the data in a standard folio. The required steps, inputs and results are described below.

In the Monte Carlo window, enter the values and select the options shown below for subpopulation 1.

Switch to subpopulation 2 and make the selection shown below.

The simulation settings are:

Click Generate. After the data has been generated, choose the 2 Subpop-Mixed Weibull distribution in the standard folio and click the Calculate icon.

The results for subpopulation 1 are shown next.

The results for subpopulation 2 are shown next.

The Weibull probability plot for this data is shown next.
