Select a distribution for the response. Different distributions appear based on characteristics of the data. For details about which distributions are available, see Available Parametric Distributions.

Compare Distributions Report and Distribution Profiler shows an example of the Compare Distributions report. The Logistic (yellow) and Exponential (magenta) distributions are shown. The plot is scaled using the Exponential distribution.
Note: Distributions for the Competing Cause report are covered in Available Distributions for Competing Cause Compare Distributions Reports.
The available distributions are listed and described in detail in Parametric Distributions. There are four major groupings of parametric distributions:
You can restrict which distributions are available by default by deselecting the ones that you do not want to appear. Select File > Preferences > Platforms > Life Distribution. The distributions listed include the Threshold, Defective Subpopulation, ZeroInflated, LogGenGamma, and GenGamma distributions. By default, all of the distributions are checked and available.

In the case of zerofailure data, none of the above distributions are available by default. However, you can uncheck the preference called Weibayes Only for Zero Failure Data. This enables you to obtain Bayesian fits for those distributions where the Bayesian Estimate option is available. See Weibayes Only for Zero Failure Data.
