transforming data with proc transreg boxcox

Hi,

I am trying to normalize some data using the proc transreg boxcox statement. The data are different scores for locomotion ability, skin and limb lesions in pigs as well as behavioural data. I used the following statement

proc transreg data=TEMP outtest=TEMPb ss2 cli;

model boxcox(variable)=identity (pig);

run; quit ;

however I get the following message in the log window ‘Output data set options specified on the PROC statement are ignored when there is

no OUT= data set’ and I get a table that is basically the same info that I get in the output window. If I ask for an output out then I get the same table and another one that supposedly contains the transformed value but rest of the data (dates, pig number, etc) is missing.

If I then I check for normality the 'transformed' value again it is not normal. Any advise in this matter will be very much appreciated as I am pretty confused and I do not know what to do next

Thanks!

Shouldn't you have an OUTPUT statement where you can specify the dataset name using the OUT=.

proc transreg data=TEMP outtest=TEMPb ss2 cli;

model boxcox(variable)=identity (pig);

output out=tempnorm ;

run; quit ;
