◤Demonstration – 4ft-Miner◢

**Main menu:**

In *params* menu (fig. 1) can be set some other
parameters as parameter *B* that is common for all quantifiers (as written
in previous section) and *handling of missing values*.

Figure 1: Parameters

Parameter *B* can be set in two ways. As an absolute number or as
a percentage. The result is that if set as an absolute number then the final
hypotheses will have number of objects satisfying both antecedent and succedent
greater or equal to number *B*.

If the parameter *B* is set as a percentage then only hypotheses with
number of objects (satisfying both antecedent and succedent) greater or equal
then *B* percent of all objects in data matrix will be displayed.

This selection gives user the possibility to decide what to do with missing
values in the matrix. It is recommended to use the default selection –
*deleting*. Other possibilities are *optimistical* and *secured*.
