Waldian t tests: Sequential Bayesian t tests with controlled error probabilities
Bayesian t tests have become increasingly popular alternatives to null-hypothesissignificance testing (NHST) in psychological research. In contrast to NHST, they allow for the quantification of evidence in favor of the null hypothesis and for optional stopping.

MAGNETOSPHERIC ACCRETION IN T TAURI STARS: OBSERVATIONAL TEST
In the classical T Tauri stars (CTTS) the magnetic field plays an important role in the interaction between the star and the accretion disk. In 1996-2000 we have carried out an extensive spectroscopic and photometric monitoring of the extremly active ...
