您要查找的是不是:
- 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。
- 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。
- 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 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。
- There are critical points to distinguish different percolation mechanism on Klinkenberg regression line. 在克氏回归曲线上,存在著界定不同渗流机理影响的临界点。
- 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。
- 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。
- 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)。
- Calculate the regression line of test results versus analyte concentrations.The correlation coefficient should be more than 0.99. 以测定结果的响应信号作为被测物浓度的函数作图,相关系数应大于0.;99。
