I'm trying to run a factor analysis but I'm having some trouble

[Tommac72584]

I imported the data as followed:

/* Generated Code (IMPORT) */
/* Source File: Hatco x1-x7.txt */
/* Source Path: /home/tmaciver7840/my_content */
/* Code generated on: Friday, June 24, 2016 3:56:21 PM */

%web_drop_table(WORK.IMPORT4);

FILENAME REFFILE "/home/tmaciver7840/my_content/Hatco x1-x7.txt" TERMSTR=CR;

PROC IMPORT DATAFILE=REFFILE
DBMS=tab
OUT=WORK.IMPORT4;
GETNAMES=YES;
RUN;

PROC CONTENTS DATA=WORK.IMPORT4; RUN;

%web_open_table(WORK.IMPORT4);

I'm good up to this point. Now I just need a little help with running a factor analysis. I appreciate any guidance. Thank you.

There are many kinds of factor analysis. The simplest is probably the principal component analysis.  The documentation for PROC FACTOR has a Getting Started example and four other helpful examples. A basic call might look like this:

ods graphics on;
proc factor data=import4 corr n=4 score outstat=ScoreOut
     method=prin rotate=varimax plots=all;
var x1-x7;
run;

If you want to produce factor scores, you can use PROC SCORE to score the model and use PROC SGPLOT to plot the results:

proc score data=import4 score=ScoreOut out=FactorScores;
   var x1-x7;
   ID ID;
run;

proc sgplot data=FactorScores;
   scatter x=Factor1 y=Factor2 / datalabel=ID;
   xaxis grid;
   yaxis grid;
   refline 0 / axis=x; refline 0 / axis=y; 
run;

Perfect. Thank you Rick.
