Dear John, Thanks for the prompt reply! Sorry did not supply with more detailed information. The target model consists of three latent factors, general risk scale from Weber's domain risk scales, time perspective scale from Zimbardo(only future time oriented) and a travel risk

Dear Hyena, Your model is of three correlated factors accounting for the observed variables. Those three correlations may be accounted for equally well by correlations (loadings) of the lower order factors with a general factor. Those two models are indeed equivalent models and will, as a

Thanks for the clear clarification. The suggested bi-factor solution sounds attractive. I am going to check it in details. regards, William Revelle wrote: Dear Hyena, Your model is of three correlated factors accounting for the observed variables. Those three correlations may be accounted

Dear hyena, Actually, looking at this a bit more closely, the first models dedicate 6 parameters to the correlational and variational structure of the three variables that you mention -- 3 variances and 3 covariances; the second model also dedicates 6 parameters -- 3 factor loadings and 3 error
