A PC is a linear combination of the input variables, not a single variable. You can see from the Principal Components Coefficient plot or table how each variable contributes to each PC. Or you can view the Score Code to see the linear equation for creating each PC variable, e.g. (JOB and REASON are nominal inputs): PC_1 = 2.4684632E-7*JOB_1_+ 8.5513858E-7*JOB_2_+ 9.0167328E-7*JOB_3_+ 2.0593746E-6*JOB_4_+ 1.6843513E-6*JOB_5_+ 1.2073992E-7*JOB_6_+ 2.8210926E-7*JOB_7_+ 2.4579164E-7*REASON_1_+ 4.0859942E-6*REASON_2_+ 1.8184475E-6*REASON_3_+ ...
