求教线性回归中决定系数R²多大算有效？R²小于几拟合就不合理
WebR 方测度 了回归直线对观测数据的拟合程度，如果说所有的观测点都落在直线上，则SSE=0，此时 R^2 =1,拟合是完全的，如果y的变化与X无关，则SSR=0，也就是 R^2 =0， 所以可以得到R方的取值范围在【0,1】，同时根据计算公式，也可以得到，R方越接近1说明SSR占SST的占比越大，也就是说明模型拟合越好 ，反之，如果R方越接近1，说明SSR Web1、用螺纹密封的管螺纹其标记及各种螺纹的特征代号规定如下： Rc—圆锥内螺纹 Rp—与圆锥外螺纹配合的圆柱内螺纹 R—圆锥外螺纹 标准规定将螺纹尺寸代号写在特征代号之后，若螺纹为械旋应再加写左旋 代号LH，具体示例如下： 圆锥内螺纹：Rc1/2 左旋 螺纹R2是多大 百度知道
