%description
Efficient design matrix free lasso penalized estimation in large scale 2
and 3-dimensional generalized linear array model framework. The procedure
is based on the gdpg algorithm from Lund et al. (2017)
<doi:10.1080/10618600.2017.1279548>. Currently Lasso or Smoothly Clipped
Absolute Deviation (SCAD) penalized estimation is possible for the
following models: The Gaussian model with identity link, the Binomial
model with logit link, the Poisson model with log link and the Gamma model
with log link. It is also possible to include a component in the model
with non-tensor design e.g an intercept. Also provided are functions,
glamlassoRR() and glamlassoS(), fitting special cases of GLAMs.
