I have this mcfa<- "impulsivity=~imp1r+imp2+imp3+imp4 physical=~phys1+phys2+phys3+phys4 risky=~risk1+risk2+risk3+risk4 selfish=~self1+self2+self3+self4 simple=~simp1+simp2+simp3+simp4r temper=~temp1+temp2+temp3+temp4 control=~impulsivity+physical+risky+selfish+simple+temper" where: the model is a second order CFA the variables are dichotomic (0-1) i'm using lavaan and I would like to use polychoric when I have the same items but polytomous i use fitcfa <- cfa(mcfa, data = data_analisis) summary(fitcfa, standardized = TRUE, fit.measure=TRUE) standardizedSolution(fitcfa, type = "std.all") anyone know what y should do to apply polychoric?
