Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model.
