Solve least squares regression and force through 0 intercept in java

Question

I am trying to get the slope for the best first line:

SimpleRegression simpleRegression = new SimpleRegression();
simpleRegression.addData(...);
...

simpleRegression.getSlope()
simpleRegression.getIntercept()

I am trying to get it to force through zero though so the formula can be reduced down to y=mx

How should I go about this?

I think this question might be useful for people who type in google: "finding least squares regression and force through 0 intercept in java" as most questions w/ this problem are done via R. — Tim Nuwin, Jan 08 '19 at 16:29

Looks like the constructor takes a true/false argument for intercept.

For my use case of not having an intercept I would have to declare: new SimpleRegression(false)
