MIXHOLD Subcommand (ORTHOPLAN command)

MIXHOLD indicates whether holdout cases should be randomly mixed with the experimental cases or should appear separately after the experimental plan in the file.

• If MIXHOLD is not specified, the default is NO, meaning holdout cases will appear after the experimental cases in the file.
• MIXHOLD followed by keyword YES requests that the holdout cases be randomly mixed with the experimental cases.
• MIXHOLD specified without a HOLDOUT subcommand has no effect.
