Fitting Penalized Logistic Regression Models Using QR Factorization
The paper presents improvement of a commonly used learning algorithm for logistic regression. In the direct approach Newton method needs inversion of Hessian, what is cubic with respect to the number of attributes. We study a special case when the number of samples m is smaller than the number of at...
