- multiple regression line 复回归线
- In this lecture we introduce the multiple regression. 在本次课中，我们介绍了多元回归。
- That is, the regression line would tend to overestimate the magnitudes of Y. 即回归线趋于过高估计了Y值。
- Computes the average of the independent variable of the regression line. 计算回归线的独立变量的平均值。
- Only age, BMI and leptin correlated to BMD by multiple regression analysis. 多元线性回归分析,仅年龄、体质量指数、瘦素与骨密度相关。
- Data were analyzed using multiple regression and canonical correlation. 所收集资料以统计方法分析进行资料处理。
- How do we think about how well our sample regression line fits our sample data? 我们怎样衡量我们的样本回归线拟合样本数据有多好呢?
- The regression line is derived from a sample and not from the entire population. 样本回归线是根据一个样本而不是根据完全总体推导出来的。
- Based on the multipl regression theory the regression tquations were established for the production of electrolytic metallic manganese. 用统计学的复回归理论,建立了电解锰生产的回归方程;
- Accordingly, the end for multiple regression as against linear regression appeared quite reasonable. 因此,同线性回归相比,这种对多元回归的需要看来是颇有道理的。
- The following example returns the intercept of a regression line for the unit sales and the store sales measures. 下例将返回单位销售额和存储销售额的回归线截距。
- Real application indicates that multiple regression formula can have high accuracy during short-term predication with high application value. 实际应用表明，建立的多元回归公式在短期预测时达到了较高的精度，具有较高的应用价值。

- Using multiple regression analysis, age, duration and RRBT were associated with RRAT (R=0.59, R 2=0.35). 前牙区RRAT校正均值为 0 5 9,后牙区为 0 12 ,差异有高度显著性。
- In a multiple regression model, age and systolic blood pressure measured at home were positively correlated with AIx. 将增强指数作为因变量 ,年龄、身高、心率、家访时的收缩压及舒张压作为自变量进行多元回归分析显示 ,受试者年龄及收缩压与增强指数呈显著的正相关。
- If the observations used in the analysis extend back in time for several years, the resulting regression line may be too steep. 如果在分析中使用的观察值扩大到几年以前，那么推导出的回归直线就会可能太悬殊。
- Multiple regression analysis showed that CTR genotypes were associated with FN BMD in postmenopausal women(P<0.05). 多元逐步回归分析提示;CTR基因型与绝经后妇女股骨颈BMD相关(P<0.;05)。
- The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line. 而估计值的平均误差，却是度量观察值围绕着回归直线的变化程度或分散程度。
- Multiple regression models can accommodate many explanatory variables that may be correlated. 多元回归模型能容许很多解释变量，而这些变量可以是相关的。
- After obtaining the set of points, the LinRegIntercept function returns the intercept of the regression line (b in the previous equation). 获取点集后,LinRegIntercept函数返回回归线的截距(前一等式中的b)。
