Syntax
>> BOX-COX
Parent Command
> PARAMETER
Subcommand
>>> NONE
Description
This command selects parameter lambda of the Box-Cox transformation as the parameter to be adjusted or estimated. To address a violation of the homoscedasticity assumption, the Box-Cox transformation can be applied to the measured and simulated data as follows:
The Box-Cox transformation relates to a data set in block >> OBSERVATION, which must contain the command >>>> BOX-COX: lambda. The data set is identified by its sequence number through subcommand >>>> INDEX.
