-===Using the Mixed Weibull Distribution in Weibull++===
+#REDIRECT [[The_Mixed_Weibull_Distribution]]
-To use the mixed Weibull distribution, simply select the Mixed Weibull Distribution from the '''Distribution''' drop down list. You can choose Mixed Weibull distribution with 2, 3, or 4 subpopulations?

-'''Viewing the Calculated Parameters'''
-When using the Mixed Weibull option, the parameters given in the result area apply to different subpopulations. To view the results for a particular subpopulation, select the subpopulation, as shown next.

-'''About the Calculated Parameters'''
-Weibull++ uses the numbers 1, 2, 3 and 4 (or first, second, third and fourth subpopulation) to identify each subpopulation. These are just designations for each subpopulation, and they are ordered based on the value of the scale parameter,  <math>\eta </math> . Since the equation used is additive or:
-::<math>{{R}_{1,..,S}}(T)=\underset{i=1}{\overset{S}{\mathop \sum }}\,\frac{{{N}_{i}}}{N}{{e}^{-{{\left( \tfrac{t}{{{\eta }_{i}}} \right)}^{{{\beta }_{i}}}}}}</math>
-the order of the subpopulations which are given the designation 1, 2, 3, or 4 is of no consequence. For consistency, the application will always return the order of the results based on the magnitude of the scale parameter.
