Abstract in brief

  • The paper discusses methods to improve the analysis of fMRI data using General Linear Models (GLMs), specifically through crossvalidated Bayesian model selection (cvBMS) and model averaging (cvBMA), to select or combine models for better accuracy.
  • cvBMS helps identify the best model for each group, reducing the risk of missing true effects, while cvBMA combines information from all models weighted by their probabilities to improve the estimation of key brain activity parameters.
  • The authors highlight that cvBMA is especially useful when regressors of interest are consistent across models, as it can enhance sensitivity to experimental effects compared to simply choosing the best model per subject or group.]
