What
do you mean SVM support? we can now train Support Vector
Machines Models within Gretl?
Yep, look in the help menu for "Gretl + SVM".
Quoting from that doc:
"Support for libsvm in gretl was added in the 2017d release
(2017-11-07). Since then, however, some improvements have been
made and at present you’ll be better off using gretl 2018a or
higher to work with this."
And from the latest changelog (2019a): "SVM support: make this
available on all platforms and drop the requirement of separately
installed libsvm"
