We also include a discussion on feature selection and provide some checkpoints for correctly implementing linear regression. The second is the more recent logistic regression method used for classification. We explain the basic concepts behind calculation of the logit and how this is used to transform a discrete label variable into a continuous function so that function-fitting methods may be applied. ...
