what is the degree of freedom when estimating a second order factor? why is my chi square negative in amos why do uncorrelated factors have negative chi square how do i constrain the chi square can you constrain a chi square in a comma model which factor would be a good first order factor for an amos model? how to constrain chi square for uncorrelated factor how to constrain correlation what is the problem when constrained factor is uncorrelated how to constrain a second order factor to be uncorrelated why is chi square negative in the unconstrained cfa model what is the error message that is sent when a factor is not uncorrelated what constrains a second order factor to be uncorrelated what is the reason for a negative chi square in a second-order factor model how to find if a second order factor has positive covariance what is a problem if you constrain a second order factor which is a negative correlation and why does it make the chi square less? how to constrain a second order factor what is the problem when you constrain the chi-square can an uncorrelated factor be constrained?
