Life Comparison-Compare Two Designs Using Comparison Wizard

Using the data presented in Example 1, use Weibull++'s Comparison Wizard to estimate the probability that units from the new design will outlast units from the old design.


Solution

After entering the Example 1 data sets into two different folios (or data sheets within the same folio) and analyzing them (in this case, the two data sets were analyzed using the two-parameter distribution and MLE), select Tests of Comparison from the Insert menu to accessthe Comparison Wizard. Specify the data sets that are being compared:
