feature request: adding support for Welch's t-test #136

Closed IndrajeetPatil closed 5 years ago

IndrajeetPatil commented 5 years ago

If I am not mistaken, currently only the Student's t-test assuming equal variances is supported?

If yes, it will also be nice to add support for Welch's t-test with an additional argument (e.g., var.equal) to ttestBF, which will be relevant for between-subjects designs.

Welch's test is specifically designed to control Type I error rate (that is inherent in its design). How would that be incorporated into the BayesFactor test?
