Significance of Goodness of fit
Goodness of fit refers to how effectively a statistical model aligns with observed data. It assesses the validity and reliability of a measurement tool by determining the degree to which predicted values match actual data. This evaluation is conducted using various indices, such as CFI, TLI, RMSEA, and SRMR, which help determine the quality of models, including linear regressions. Overall, goodness of fit measures the accuracy of a model's representation of the data in statistical analyses.

The concept of Goodness of fit in scientific sources
Goodness of fit is a statistical measure evaluating how well a model aligns with observed data, indicating the accuracy and reliability of the model in analyzing the dataset in question.

(1) This is a statistical test to determine how well a model fits the observed data, helping to validate the model.[1] (2) Goodness-of-fit refers to how well the data from the study aligns with the proposed model or structure, indicating the validity of the measurement tool.[2] (3) This refers to the overall measure of how well the proposed model fits the observed data, which was evaluated using various indices in the confirmatory factor analysis.[3] (4) This refers to the degree to which the data aligns with the proposed model, which is assessed using various indices like CFI, TLI, SRMR, and RMSEA, and the model's fit can be evaluated.[4] (5) Goodness-of-fit refers to the extent to which a statistical model fits the observed data, with various indices used to assess how well the model represents the data.[5]
