Description: Contains a workable R script to apply SPRT t-tests

License: CC-By Attribution 4.0 International


This script implements Abraham Wald's (147) Sequential Probability Ratio Test for the test of a normal mean (difference) with unknown variance in R. The script implements the sequential t tests developed by Rushton (1950, 1952), commonly referred to as Barnard's t test, and Hajnal (1961). It contains R code to perform one- or two-sided t tests with one, two paired, or two independent samples.
