Dear statalister

While reporting the scores, I am also mentioning the eigenvectors,
just wanted to clarify that my scoring coefficients are the
eigenvectors only, right or when reporting them to be the factor
scores do I have to scale them by anything? I am using the command
'polychoricpca (variable list), score(index) nscore(1).
I am giving below the characteristics and also the eigenvectors
attached with them, looking at these can I say that 'availing credit/
loan (q414), beneficiary under insurance schemes, ownership of pump
sets, ownership of tractors' contribute most to the equation for

Characteristic	Factor scores
availing credit/ loan (q414)	0.405001
beneficiary under insurance schemes (q419)	0.447046
years of education for household head	0.174885
member of a society (q439)	0.318971
ownership of livestock	0.330761
ownership of pump sets	0.382785
ownership of tractors	0.390981
number of income sources	0.187382
age of household head	0.086749
total number of members	0.228836
