### Interpreting normalized value in logistic regression

I'm trying to interpret results from my logistic regression. I normalized the values between 0 and 100 because I had many variables with different units. My intercept is -0.741 and I'm using that to ...

### Newton's method and the Hessian for Softmax Logistic Regression

I'm having some trouble with optimising softmax regression via Newton's method. I'm not sure if the problem is arising with my equations for the Hessian and Gradient or with the code I've written. For ...
