Statistical / data mining methods in R and not in SAS?
...ining methods that are available in R
that are not in SAS ? With SAS I mean the SAS System Version 9.4 and SAS
Enterprise Miner. I don't expect a complete list, just two or three examples
or hints where and what to look for.
I found some older comparisons, and the R methods mentioned there (GLMET, RF,
ADABoost) are now supported by SAS (at least to some degree).
And there exists a (massive) list of available models for the caret package
here: https://rdrr.io/cran/caret/man/models.html, but it's hard to analyze the
complete list.
(I'm trying to answer a question of a colleague)....

glmnet on Autopilot
...imulations using the glmnet package. I need to use an
'automated' method for model selection at each iteration of the simulation.
The cv.glmnet function in the same package is handy for that purpose.
However, in my simulation I have p >> N, and in some cases the selected
model from cv.glmet is essentially shrinking all coefficients to zero. In
this case, the prediction for each instance equals the average of the
response variable. A reproducible example is shown below.
Is there a reasonable way to prevent this from happening in a simulation
setting with glmnet? That is, I'd like...
