生成线性回归算法java代码

当然可以！以下是生成线性回归算法Java代码的示例：

import java.util.ArrayList;

public class LinearRegression {
    private double slope;
    private double intercept;

    public LinearRegression(ArrayList<Double> xVals, ArrayList<Double> yVals) {
        double xSum = 0;
        double ySum = 0;
        double xySum = 0;
        double xSquaredSum = 0;

        for (int i = 0; i < xVals.size(); i++) {
            xSum += xVals.get(i);
            ySum += yVals.get(i);
            xySum += xVals.get(i) * yVals.get(i);
            xSquaredSum += xVals.get(i) * xVals.get(i);
        }

        int n = xVals.size();

        slope = (n * xySum - xSum * ySum) / (n * xSquaredSum - xSum * xSum);
        intercept = (ySum / n) - slope * (xSum / n);
    }

    public double getSlope() {
        return slope;
    }

    public double getIntercept() {
        return intercept;
    }

    public double predict(double xVal) {
        return slope * xVal + intercept;
    }
}

希望这可以帮到你！
