set


SYNOPSIS

set  {field_list=<comma/hyphen separated list>  \
    attribute={INCLUDED | EXCLUDED}  \
    | object_list=<comma/hyphen separated list>  \
    attribute={TRAININGSET | EXCLUDED | TESTSET} \
    | id_list=<comma/hyphen separated list>  \
    attribute={TRAININGSET | EXCLUDED | TESTSET}}


DESCRIPTION

The set keyword is used to set fields as excluded from the analysis (attribute=EXCLUDED) without actually removing them permanently as would happen with the remove_fields command; in fact, subsequently they can be reactivated setting attribute=INCLUDED. The set keyword may also operate on objects, setting them as excluded (attribute=EXCLUDED) without actually removing them permanently as would happen with the remove_objects command. Additionally, in the case of objects the attribute parameter can assume two more values, namely TRAININGSET (which is a synonym of INCLUDED) and TESTSET, which respectively set objects as belonging to the training set, and therefore taken into account in all pretreatment, PLS model building and variable selection operations, or to the test set, which comes into play only when the model predictivity is challenged against an external validation set.

EXAMPLES

# the following commands assign objects from 1 to 20 to the training set, and objects from 21 to 26 to the test set
set  object_list=1-20  attribute=TRAININGSET
set  object_list=21-26  attribute=TESTSET

# the following command temporarily sets as inactive field 1
set  field_list=1  attribute=EXCLUDED
