A Laplace equation approach to the Behrens--Fisher problem
Nagananda K G, Jong Sung Kim
We develop a partial differential equation formulation of the Behrens-Fisher problem for two independent normal samples with unknown and unequal variances. An orthogonal decomposit…

A unified approach to the Behrens-Fisher problem
Nagananda K G, Jong Sung Kim
A unified framework is presented to study the two-sample Behrens--Fisher problem -- testing equality of means when two normal populations have unequal, unknown variances -- and a c…
