WebApr 22, 2024 · Goodness-of fit is evaluated using a range of model fit indices, which assess the relationship between the observed data and the theoretical data which would be expected from the model. Model fit indices can be used with either thresholds or hypothesis testing to reject or retain the proposed model (Costa & Sarmento, 2024 ).

WebIt indicates the goodness of fit of the model. R-squared has the useful property that its scale is intuitive. It ranges from zero to one. Zero indicates that the proposed model does not improve prediction over the mean model. One indicates perfect prediction. Improvement in the regression model results in proportional increases in R-squared.
