- The Tucker-Lewis index (TLI) is a measure of how well a model fits the data123. It is also known as the non-normed fit index (NNFI)123. It is based on the comparison of the null model (no relationships among variables) and the target model (the hypothesized model)23. It ranges from 0 to 1, where 1 is a perfect fit23. It penalizes for adding model parameters, meaning that simpler models are preferred3.Learn more:✕This summary was generated using AI based on multiple online sources. To view the original source information, use the "Learn more" links.The Tucker-Lewis index (TLI; Tucker & Lewis, 1973), also known as the non-normed fit index (NNFI; Bentler & Bonett, 1980), is one of the numerous incremental fit indices widely used in linear mean and covariance structure modeling, particularly in exploratory factor analysis, tools popular in prevention research.experts.umn.edu/en/publications/incremental-mode…
The non-normed fit index (NNFI; also known as the Tucker–Lewis index, as it was built on an index formed by Tucker and Lewis, in 1973) resolves some of the issues of negative bias, though NNFI values may sometimes fall beyond the 0 to 1 range.
en.wikipedia.org/wiki/Confirmatory_factor_analysisRanges from 0 to 1, where 1 is a perfect fit. The NFI is difference between the null model’s chi-square and the target model’s chi-square, divided by the null model’s chi-square. Tucker-Lewis Index (TLI): unlike the Bentler-Bonnett, this index, also called the non-normed fit index, penalizes for adding model parameters.

Confirmatory factor analysis - Wikipedia
In CFA, several statistical tests are used to determine how well the model fits to the data. Note that a good fit between the model and the data does not mean that the model is “correct”, or even that it explains a large proportion of the covariance. A “good model fit” only indicates that the model is plausible. When reporting the results of a confirmatory factor analysis, one is urged to report: a) the proposed models, b) any modifications made, c) which measures identify each lat…
