The value of 
producing the maximum log likelihood
is returned in the macro variable &BOXCOXAR.
The value of the variable &BOXCOXAR is "ERROR"
if the %BOXCOXAR macro is unable to compute
the best transformation due to errors. This may be
the result of large lambda values. The Box-Cox
transformation parameter involves exponentiation of
the data, so that large lambda values may cause
floating-point overflow.
Results are printed unless the PRINT=NO option is specified. Results are also stored in SAS data sets when the OUT= option is specified.
