How are you?
I use the polychoric matrix produced from the polychoric macro(25010 - Create a polychoric correlation or distance matrix) as an input data for proc factor. But I don't understand the first note. Can anyone please enlighten me on how to address this? Thank you very much.
%polychor(data=tmp, var=r1 r2 r3 r4 r5 r6 r7 r8, out=chor,type=corr);
proc factor data = chor method = ml rotate = promax outstat = FAstats n=3 heywood residuals msa score;
NOTE: N not equal across variables in data set WORK.CHOR. This may not be appropriate. The smallest value will be used.
NOTE: 3 factors will be retained by the NFACTOR criterion.
NOTE: Convergence criterion satisfied.
NOTE: The data set WORK.FASTATS has 56 observations and 10 variables.
NOTE: At least one W.D format was too small for the number to be printed. The decimal may be shifted by the "BEST" format.

I just read its SAS note.
Does it mean I need to perform listwise deletion on my data before using the polychor macro?
Thank you very much.
