Benign Breast Disease Prediction

================================

Builds a classifier using regularized logistic regression on

matched control-case data from studies on the risk factors associated

with benign breast disease.

## Building The Model

   * *Algorithm*: Logistic regression

 

   * *Enhancements*: 

      * Quadratic features were generated from the 12 features in the data set.

      * The features were regularized, and the accuracy measure on the data set

        touched 95.5% at a factor of 1.0, increasing as the factor was decreased.

        The increasing accuracy with decreasing regularization is most probably

        an indicator of over-fitting the current data.

## About The Data

   * *Name*: Benign Breast Disease 1-3 Matched Case-Control Study (BBDM13.DAT)

   * *Source*: [University of Massachusetts - Amherst](http://www.umass.edu/statdata/statdata/stat-logistic.html)

   * *Size*: 200 observations, 14 variables

   * *Type*: Matched case-control

   * *Original Source*: These data come from Hosmer and Lemeshow (2000) Applied Logistic

 	                    Regression: Second Edition, page 245. These data are copyrighted
