Simulation study of an implementation of Abraham Wald's (1947) *Sequential Probability Ratio Test* for a two-sided two-sample *t* test (Hajnal, 1961).
This project contains the R scripts for all simulations and analysis, as well as the data reported in "Controlling decision errors with minimal costs: The sequential probability ratio *t* test". Moreover, a workable R script to apply sequential *t*-tests can be obtained.
