Usage

From source file:dfs.OLSTrendLine.java

    for (int i = 0; i < x.length; i++) {

        xData[i] = xVector(x[i]);
    }
    if (logY()) { // in some models we are predicting ln y, so we replace each y with ln y
        y = Arrays.copyOf(y, y.length); // user might not be finished with the array we were given
        for (int i = 0; i < x.length; i++) {

    ols.setNoIntercept(true); // let the implementation include a constant in xVector if desired
    ols.newSampleData(y, xData); // provide the data to the model
    coef = MatrixUtils.createColumnRealMatrix(ols.estimateRegressionParameters()); // get our coefs
