#ERA Toolbox Wiki

##Description

The ERP Reliability Analysis (ERA) toolbox is an open-source Matlab program that uses generalizability (G) theory to evaluate the reliability of ERP data. The purpose of the toolbox is to characterize the dependability (G-theory analog of reliability) of ERP scores to facilitate their calculation on a study-by-study basis and increase the reporting of these estimates.

The ERA toolbox provides information about the minimum number of trials needed for dependable ERP scores and describes the overall dependability of ERP estimates. All information provided by the ERA toolbox is stratified by group and condition to allow the user to directly compare dependability (e.g., a particular group may require more trials to achieve an acceptable level of dependability than another group).

The formulas implemented in the ERA Toolbox were developed by Dr. Scott Baldwin. Information about the formulas can be found in the following paper:
