plot.abess

Produces a coefficient/deviance/tuning-value plot
for a fitted "abess" object.

Extremely efficient toolkit for solving the best subset selection problem <https://www.jmlr.org/papers/v23/21-1060.html>. This package is its R interface. The package implements and generalizes algorithms designed in <doi:10.1073/pnas.2014241117> that exploits a novel sequencing-and-splicing technique to guarantee exact support recovery and globally optimal solution in polynomial times for linear model. It also supports best subset selection for logistic regression, Poisson regression, Cox proportional hazard model, Gamma regression, multiple-response regression, multinomial logistic regression, ordinal regression, (sequential) principal component analysis, and robust principal component analysis. The other valuable features such as the best subset of group selection <doi:10.1287/ijoc.2022.1241> and sure independence screening <doi:10.1111/j.1467-9868.2008.00674.x> are also provided.

plot.abess function

<dl><dt>x</dt>
<dd>A "<code>abess</code>" object.</dd>
<dt>type</dt>
<dd>The type of terms to be plot in the y-axis.
One of the following: <code>"coef"</code> (i.e., coefficients),
<code>"l2norm"</code> (i.e., L2-norm of coefficients),
<code>"dev"</code> (i.e., deviance),
and <code>"tune"</code> (i.e., tuning value).
Default is <code>"coef"</code>.</dd>
<dt>label</dt>
<dd>A logical value.
If <code>label = TRUE</code> (the default),
label the curves with variable sequence numbers.</dd>
<dt>...</dt>
<dd>Other graphical parameters to plot</dd></dl>
