[Feature Request]: Sequential analysis with informed prior on Bayesian independent samples t-test #1719

Open andrewsjan opened 2 years ago

andrewsjan commented 2 years ago

Description

The sequential analysis option is available for the Bayesian independent samples t-test using the default prior but not with an informed prior.

Purpose

Sequential analysis would be useful with an informed prior for the same reasons it is useful with an unformed prior.

Use-case

I am using the BFDA sequential testing approach with an informed prior so need the sequential analysis to determine when to stop collecting data. We can obtain this ourselves using r but it would be nice to also be able to get it from JASP, as one can when using the default prior. Thank you.

Is your feature request related to a problem?

Not really, it would just be convenient to have this option.

Describe the solution you would like

Add the sequential analysis option for the Bayesian independent samples t-test using an informed prior.

Describe alternatives that you have considered

Generating it ourselves outside of JASP.

Additional context

I hope the request is straightforward and clear.

Hi @andrewsjan, thanks for the request. @vandenman any idea if that is feasible?
