This step allows you to change the percentage split between the build and test tables and to randomize the data before splitting.
The wizard displays the number of cases (rows) in the table or view as Total Case Count.
The slider indicates how the cases are split between the build table and the test table. The default splits are as follows:
You can change these values by moving the slider. Sliding to the left increases the size of the test table; to the right, of the build table. As you move the slider, the Count and Percent values below Build Table and Text Table are changed to reflect the position of the slider.
Neither percent can be 0 or 100.
Click the Randomize Before Split check box to randomize the data during the split operation. If you have already applied the sample or stratified sample transformation to the table or have otherwise randomized the table, make sure that this option is not checked.
Click Next to continue.
The wizard validates that neither the test or the build percent is 0 or 100.
