Logistic Regression, reference category for predictors

Is it possible to choose a reference category for predictor variables in the logistic regression node? For example, making 'Placebo' and 'F' the reference categories for treatment and sex, respectively. 

Solved. Using a Rule Engine node before LR making '1. Placebo' the first category (reference):                 $Treatment$ = "Placebo" => "1. Placebo"  
$Treatment$ = "Drug A" => "2. Drug A"
$Treatment$ = "Drug B" => "3. Drug B"

 

Hi Alfroc,

thank you for sharing the solution :-)

Best, Iris
