Description Usage Arguments Details Value References Examples
The Bayesian LASSO of Park & Casella (2008), but with the allowance for a set of covariates that are not penalized.
For example, you may wish to include variables such as age and gender in all models so that
the coefficients for the other variables are penalized while controlling for these. This
is a common need in research.
Note only the Gaussian likelihood is provided because the Bayesian LASSO requires conditioning
on the error variance, which GLM-families do not have. If you need to use the LASSO for a poisson or binomial regression, I suggest taking
a look at extLASSODC
Alternatively, utilizing bridgeDC
with kappa = 1
yields the New Bayesian LASSO, which is a re-parameterization of the Bayesian LASSO utilizing a scale mixture of
uniform distributions to obtain the Laplacian priors (Mallick & Yi, 2014).
