Shows the response surfaces of the failure probability versus individual explanatory and response variables. See the Profilers book.

Shows the response surfaces of the response variable versus the explanatory variable and the failure probability. See the Profilers book.

Separate Location is a probability plot assuming equal scale parameters and separate location parameters. This is useful for assessing the parallelism assumption.

Separate Location and Scale is a probability plot assuming different scale and location parameters. This is useful for assessing if the distribution is adequate for the data. This plot is not shown for the Exponential distribution.

Regression is a probability plot for which the distribution parameters are functions of the X variables.
