This is a web-based interface for the R Sequential package, with which you can conduct exact sequential analyses for binomial and Poisson data. It allows you to run the R Sequential package online, without installing and managing an R programming environment, and without writing any code in the R programming language. Functions to calculate statistical power, expected time to signal and required sample sizes for performing exact sequential analysis are also provided. All these calculations can be done for either Poisson or binomial data, and for different types of rejection boundaries. In the case of group sequential analyses, the group sizes do not have to be specified in advance.

For complete documentation, please read the R Sequential User Guide and the scientific papers in the reference list.

This site is currently using selected functions from R Sequential version 2.3.2.
