[R-pkgs] updated package eba 1.4-0

[Florian Wickelmaier]

Dear all,

There is an updated version of the eba package for
elimination-by-aspects (EBA) choice models available on CRAN.

It features new functions for extracting and plotting
the residuals, for testing hypotheses on the parameters
(wald.test), and for comparing sub-samples (group.test).
The documentation has also been updated.
Any feedback is welcome.

Happy modeling!

Florian Wickelmaier
