For my research I am using SmartPLS version 3.2.4 for data analysis. I have obtained the following model fit values:
Saturated Model Estimated Model
SRMR 0.068 0.068
d_ULS 4.552 4.552
d_G 5.969 5.969
Chi-Square 2,378.253 2,378.253
NFI 0.659 0.659
rms Theta 0.157
I have some difficulties to interpret them, in particular the geodesic discrepancy dG, the unweighted least squares discrepancy dULS and the RMStheta. I would highly appreciate to have an expert’s view on these data and some advice on their interpretation.

Re: Model Fit
Necessary caution in interpreting the chi-square value, NFI, RMS Theta etc. However GoF index of CB-SEM is different to be applied in PLS-SEM.

Re: Model Fit
I agree caution should be taken in interpreting the chi-square value, NFI, RMS Theta etc in SmartPLS. However, SRMR, seems to be a reasonable index to evaluate model fit.

Re: Model Fit
Dear Rama
I see in your model that the saturated and estimated models values are equal. Do you know what this means?
Thank you

Re: Model Fit
If you model is fully saturated the estimated and saturated model will necessarily be equivalent.

Re: Model Fit
How can i described the model fit in my paper. As a new researcher i need to know how can i write it in my papaer. Can Anyone help me?
