Problem Note 56547: Constant model variables might cause errors in PROC HPQUANTSELECT

DetailsHotfixAboutRate It

The HPQUANTSELECT procedure might issue an error if any of the variables specified in the MODEL statement have very small constant values. Possible error messages include:

ERROR: Invalid Operation.
ERROR: Termination due to Floating Point Exception
ERROR: A floating point exception or access violation occurred that prevents progress of the analysis.

If the dependent variable has a constant value of zero, you can circumvent the problem by creating an alternative near-zero and near-constant variable to use in the model. For example, if the dependent variable is y, a variable such as the following New_y could be used instead:

New_y = 1e-12 * rannor(seed);

Similarly, if the dependent variable is near zero and constant, you can circumvent the problem by creating a new variable and introducing a small amount of variation:

New_y = y + 1e-12 * rannor(seed);

There is no circumvention for the problem if an error is caused by a very small constant effect (independent variable) in the model.
