Non-central t distribution and the power of the t test: A rejoinder [PDF]
Non-central t distribution needed for assessing the power of the t test is described. Three approximations are compared and their merits discussed in regard to simplicity and accuracy.

Comparison of the empirical variances and mean values of normally distributed populations of nuclear counts [PDF]
This paper discusses the possibility of applying the F-test and double t-test in problems related to the identification of number of radioactive isotopes in a contaminated area by using only counters for radiation detection.

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 ...
