Hello, I am conducting principal component analysis using SAS University and I am noticing that in my factor structure output the variable name is repeating twice (screen shot attached). When I ran the PCA using a smaller sample (N=20) I did not see the variable repeated in the output, but I am seeing it with a larger sample (N=347). Is it normal to see the variable repeated twice? If it is normal - will this affect my results? If it is not normal, can anyone recommend how to resolve this issue? Below is the code that I used. Thanks, Naheed PROC FACTOR DATA=combined2 SIMPLE METHOD=PRIN PRIORS=ONE MINEIGEN=1 SCREE ROTATE=Varimax; VAR Q17_1 Q17_2 Q17_3 Q17_4 Q17_N5 Q17_6 Q17_7 Q17_N8 Q17_9 Q17_10 Q17_11 Q17_12 Q17_13 Q17_14 Q17_N15 Q17_16 Q17_17 Q17_18 Q17_19; run;
