Running Factor Score with Polychoric Correlation

[ssahr]

I'm trying to get factor scores for my data set using polychoric correlation. I am trying to follow the same precedure one would use for Pearson Correlation. The following Pearson Correlation runs fine:

proc factor data=Diss.Impact method=principal score outstat=Diss.Fact;
var Impact_ELLs Impact_curric Impact_acheive Impact_manage Impact_teach;
run;

proc score data=Diss.Impact score=Diss.Fact out=Diss.FScore;
var Impact_ELLs Impact_curric Impact_acheive Impact_manage Impact_teach;
run;

After I run the proc factor, the factor statistics table  gives me the correlations, eigenvaules, patters, and scores in the Diss.Fact file. When I run proc score, I get a new data set with my five variables and Factor score for each case. 

So, to get the polychoric correlation stats, I run:

proc corr data=Diss.Impact polychoric;

var Impact_ELLs Impact_curric Impact_acheive Impact_manage Impact_teach;

run;

I have created a new factor statistics table with the polychoric correlation stats but I cannot produce the coefficient score needed to run the proc score test correctly. I get this error:

ERROR: No observation of scoring coefficients having _TYPE_='SCORE' is found in the SCORE= data set.

How does one create the scoring coefficients when trying to produce factor score in a polychoric correlation? 

I'm using SAS 9.3

Take a close look at the actual contents of the data set you generated with Proc factor, maybe print all or part of it.

Then take a look at the data set created by Proc Corr (which you don't show in your code).

Proc Score is expecting some specific bits that aren't in the default output of Proc Corr. You likely need to make a pass with a data step to add as a minimum a character variable named _type_ with values of SCORE.
