Significance of Model fit
Model fit refers to how effectively a proposed measurement model corresponds with the observed data, which is evaluated using fit indices like CFI, RMSEA, and SRMR. It measures the degree of alignment between the data and the hypothesized model, which can be improved through techniques such as item removal or adjusting correlated residuals. An accurate model fit indicates a reliable representation of the variable relationships, as demonstrated by acceptable fit values in studies evaluating tools used among Malaysian university students.

The concept of Model fit in scientific sources
Model fit refers to the degree of alignment between a proposed statistical model, particularly in confirmatory factor analysis (CFA), and the observed data. It is assessed using various indices, including CFI, TLI, SRMR, and RMSEA.
(1) This refers to how well the hypothesized five-factor model fit the data obtained, and the initial model displayed a poor fit, with the CFI, TLI, and WRMR not within the acceptable threshold.[1] (2) Model fit refers to how well the proposed model fits the observed data, and is assessed using fit indices like χ 2/df, TLI, CFI, and RMSEA to evaluate the appropriateness of the DEBQ structure.[2] (3) This is a measure of how well a statistical model, such as the CFA model, fits the observed data, indicating the model's accuracy in representing the data.[3] (4) Model fit refers to the degree to which the proposed model aligns with the observed data, indicating how well the model represents the relationships among the variables.[4] (5) The study's final model demonstrated acceptable values, indicating that the scale is a suitable tool to be used among Malaysian university students and fits the data well.[5]
(1) The model fit statistics for the ZIP model and the standard Poisson model are summarized in a table, showing the AIC values, where a lower AIC indicates a better fit when accounting for model complexity.[6]
(1) This refers to the degree to which the data align with the hypothesized structure of the psychosis screening questionnaire, as evaluated in the study, according to the text.[7] (2) The degree to which the statistical model accurately represents the observed data, as indicated by goodness-of-fit indices such as χ2, TLI, and RMSEA.[8] (3) This refers to the extent to which a statistical model accurately represents the observed data, with various measures used to evaluate how well the model fits the data.[9]
