WebMar 26, 2024 · The Akaike information criterion (AIC) is a mathematical method for evaluating how well a model fits the data it was generated from. In statistics, AIC is used to compare different possible models and determine which one is the best fit for the data.

WebJan 24, 2024 · Summary. In Bayesian statistics, the marginal likelihood, also known as the evidence, is used to evaluate model fit as it quantifies the joint probability of the data under the prior. In contrast, non-Bayesian models are typically compared using cross-validation on held-out data, either through k -fold partitioning or leave- p -out subsampling. WebJun 7, 2010 · The fit indices were found to have differential sensitivity to different types of misspecification in either the mean or covariance structures with severity of misspecification controlled. No fit index was always more (or less) sensitive to misspecification in the marginal mean structure relative to those in the covariance structure.

Sample size is expected to induce variation in fit indices due to the aforementioned bias of the underlying χ 2 statistic. As fit indices often rely on χ 2 values, they inherit their sample size biases (e.g., Fan and Sivo 2007).Additionally, the size of the model is deemed to harm the precision of generic …
