Analyses

Save time by analyzing your data with EyeOpenR, our unique and easy to use analysis wizard in EyeQuestion. Analysis are based on the popular statistical language “R” and created, validated and supported by Qi Statistics. EyeOpenR offers dynamic online charts which can be exported to Excel for editing. Data filters on Assessor, Data Type, Session, Sample prior to analysis for data quality check. Data can be imported and run custom auto reports.
