By
A column or columns whose levels define separate analyses. For each level of the specified column, the corresponding rows are analyzed using the other variables that you have specified. The results are presented in separate reports. If more than one By variable is assigned, a separate report is produced for each possible combination of the levels of the By variables.
Number of Trees
Specifies the number of decision trees in the bootstrap forest model. The default value is 100.
Set Random Seed
Sets the seed for the starting values that are used in the fitting procedures. Set Random Seed is useful if you want to reproduce an analysis. If you set a random seed and save the script, the seed is automatically saved in the script.
