Plotting problem [lars()/elasticnet()]
...)|^(-gamma) gamma>0 and j = 1,...,p
2. define x_new(j) <- x(j)*w(j)
3. apply LARS to solve modified lasso problem
out.adalasso <- lars(X_new,y,type="lasso") or enet(X_new, y,
lambda=0)
suppose, the estimated coefficients are beta_new(j), j=1,...,p
4. beta_adalasso <- beta_new(j)*w(j)
everything went fine except I am having problem in plotting standardized
(adaptive lasso) coefficients vs. |beta|/max(|beta|). It seems that
plot(out.adalasso) provides plot for beta_new. How can i get similar plot
for beta_adalasso.
