ERA Toolbox

The ERP Reliability Analysis (ERA) Toolbox uses generalizability theory as a method for evaluating the psychometric reliability of ERP data. Dependability (and some generalizability) estimates (generalizability-theory analog to reliability) can be computed for any number of events, groups, or occasions. The influence of number of trials on dependability of measurements will also be determined, and a recommended cutoff for inclusion of ERP data will be provided based on the stability of measurement as the number of trials included in a single-subject average for a given group and event increases. The Toolbox can also estimate the psychometric internal consistency of difference scores.

See the User Manual or wiki for more information about the ERA Toolbox.
