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
http://www.gnu.org/software/gsl/manual/html_node/Linear-regression.html
so you can transform your data so the logistic model becomes a linear
model and then use the linear regression provided by GSL.
