ruby_linear_regression 0.1.1

An implementation of a linear regression machine learning algorithm implemented in Ruby. Features: - Supports simple problems with one independent variable to predict a dependent variable and multivariate problems with multiple independent variables to predict a dependent variable. - Supports training using the normal equation - Supports training using gradient descent - The library is implemented in pure ruby using Ruby's Matrix implementation. An example of how to use the library can be found in the blog post: [Implementing linear regressing using Ruby](http://www.practicalai.io/implementing-linear-regression-using-ruby/).
