Modeling Tools• PlanEditor.exe (Interactive)

Specify roles (e.g. input vs output) anddistributions for variables

• Dnet.exe (Command line)Build a dependency network or Bayesiannetwork from data

• DnetBrowser.exe (Interactive)Interactively browse dependency network orBayesian network

• DnetLogscore.exe (Command Line)Evaluate Prediction accuracy of models

Built-In Help: -help Option

c:\WinMine Toolkit\Bin>datacheck -helpThis executable parses a data file and prints outsummary statistics.

If a marginal statistics file is provided with the'-marg' flag, the executable collects marginal countsfor each variable and prints them to that file.
