Hi Dr. Muthen, I am running a model with sample size=200. The chi-square is significant but other fit indexes are quite acceptable. The sample size might not be the cause of the significance of because it is not large. Therefore the only reason I can figure out is that the assumption of data normality is invaded. Am I correct? If so, how can I test the normality of the data? Then what can I do to improve the model fit? Thanks.
