The PHPP assumes that the data set is a representative sample of the underlying process generating the data. Hence, the data set contains all representative sample of possible values for numerical valued entities.

The PHPP creates as many intervals as specified by the user with the number of different values in the data set being an upper limit.

To increase (or decrease) the number of intervals created by PHPP the HUGIN GUI can be used for post-processing of the constructed model. The HUGIN GUI can also be used to create the necessary intervals for selected variables prior to model construction. This can be achieved using the <ph -update> command as described here
