That does not make sense to me.  Logistic regression applies a hinge function 
to the linear combination of the inputs, not to the individual inputs 
themselves.  The training of a logistic regression model cannot be framed as a 
composition of a data transformation followed by a linear regression.

There is support for linear regression

so you can transform your data so the logistic model becomes a linear
model and then use the linear regression provided by GSL.
