3. Click Simulate.
4. Click the Make Table button under the Simulate to Table node.
Doing these steps for both the original and noise-factor-optimal simulations results in two similar data
tables, each holding a simulation. In order to make two comparable histograms of the predictions, we need
the two prediction columns in a single data table.
5. Copy the Pred Formula HARDNESS column from one of the simulation tables into the other table.
They must have different names, like Without Noise Factor and With Noise Factor.
6. Select Analyze > Distribution and assign both prediction columns as Y.
7. When the histograms appear, select Uniform Scaling from the Distribution main title bar.
