sse(sum of squared error)系数 SSE(Sum of Squared Errors)系数是用于衡量回归模型拟合效果的一个指标。它表示模型预测值与实际值之间的平方误差的总和。 假设我们有一个回归模型ŷ=β0+β1x1+β2x2+...+βpxp\hat{y} = \beta_0 + \beta_1 x_1 + \beta_2 x_2 + ... + \beta_p x_phat...
误差平方和(Sum of Squared Errors, SSE),也称为残差平方和,是统计学和机器学习中常用的一个概念。它表示观测值与预测值(或拟合值)之间差异的平方和。误差平方和是衡量模型拟合优度的一个重要指标,值越小表示模型拟合得越好。 2. 给出计算误差平方和的公式 误差平方和的公式为: [ SSE = \sum_{i=1}^{n...
