The distribution
keyword allows the user to select between a cumulative distribution/belief/plausibility function and a complementary cumulative distribution/belief/plausibility function. This choice affects how probabilities and reliability indices are reported.
Default Behavior
If the distribution
keyword is present, it must be accompanied by either cumulative
or complementary
. Otherwise, a cumulative distribution will be used by default.
Expected Outputs
Output will be a set of model response-probability pairs determined according to the choice of distribution. The choice of distribution also defines the sign of the reliability or generalized reliability indices.
