Train a LinearRegression model given an RDD of (label, features) pairs.
Train a LinearRegression model given an RDD of (label, features) pairs. We run a fixed number of iterations of gradient descent using a step size of 1.0. We use the entire data set to compute the true gradient in each iteration.
RDD of (label, array of features) pairs. Each pair describes a row of the data matrix A as well as the corresponding right hand side label y
Number of iterations of gradient descent to run.
a LinearRegressionModel which has the weights and offset from training.

Train a LinearRegression model given an RDD of (label, features) pairs. We run a fixed number
of iterations of gradient descent using the specified step size. Each iteration uses
miniBatchFraction
fraction of the data to calculate a stochastic gradient.
