mphase1
Methods print
and plot
allow to write
to the console and plot (optionally changing the layout)
the result of the Phase I analysis performed with function
mphase1
.
Method postsignal
implements the post-signal Phase I analysis
based on the adaptive LASSO described in Capizzi and Masarotto (2016).
It uses the p-value and the results on the forward search
contained in its first argument. Hence, it is
useful for re-running the analysis with different values
of alpha
and/or gamma
.
