Multi-Linear Regression OLS in java ( Weka)

Hi there,

I was just wanting confirmation that this function: weka.classifiers.functions.LinearRegression, uses the OLS algorithm, closed form.
I found from this link below:

Also I have been trying to find a sample example in java of Multi-Linear Regression that not only returns the coefficients, but also returns many more statistics such as,
standard error of the coefficients, t-statistics of coefficients, p-values, F-test value, residuals, R.

On the web I only found one example which just returns the coefficients and nothing more.

Hope someone knows of some examples or resources on Multi-Linear Regression in java using Weka.

Regards.
