Function free1way implementing semiparametrically efficient inference
procedures (likelihood- and permutation-based) in distribution-free
stratified K-sample oneway layouts was added to the stats
package. Approximate (via power.free1way.test) and
simulation-based (utilising rfree1way for random number
generation) power-assessment and sample-size planning as well as
model diagnostics (available from a plot method and
probability-probability plots in ppplot) complement the
functionality. Package free1way.docreg provides additional
documentation and regression tests.
