AgreeStat 360 is a software that you can use to perform statistical analysis on the extent of agreement among multiple raters. It has a cloud-based and an Excel-based versions. It is self-contained, requires no installation and only a web browser is needed for you to run the cloud-based version. You can allocate the subjects being rated into separate groups and perform sub-group analyses in batch mode.

Note that the same license key you purchase here allows you to use the Excel version (Windows only) of AgreeStat 360 as well as the cloud version. Both the cloud and Excel versions of AgreeStat 360 require separate registration processes, but use the exact same license key you will receive by email right after completing the purchase.

AgreeStat 360 can compute Chance-corrected Agreement Coefficients (CAC), as well as Intraclass Correlation Coefficients (ICC). This program is unique in its ability to handle missing data for both chance-corrected and intraclass correlation coefficients. Weighted kappa and other agreement coefficients can be computed using one of 7 predefined weights. You also have the option to use custom weights that only you can specify. With AgreeStat 360, you can compute Cohen's Kappa, Conger's generalized Kappa, Gwet's AC1 / AC2, Krippendorff's Alpha, Brennan-Prediger's coefficient and various intraclass correlation coefficients. You will also be able to compute the standard errors and confidence intervals associated with these coefficients.
