标准回归误差(Standard Error of the Regression) 标准回归误差(Standard Error of the Regression,简称SER)是回归分析中一个重要的统计量,它衡量了回归线与实际观测值之间的离散程度,即预测值与实际值之间误差的标准差。 如何计算标准回归误差 标准回归误差的计算公式为: [ SER = \sqrt{\frac{\sum_{i=1}^{n...
R-squared is a percentage, which seems easy to understand. However, I often appreciate the standard error of the regression a bit more. I value the concrete insight provided by using the original units of the dependent variable. If I’m using the regression model to produce predictions, S t...
In regressions, the standard error is an absolute measure of how far data points tend to deviate from the regression line in general.
Overall, the findings underline the need for clearly stated and consistent analytical methods in producing papers as well as for careful review and selection of papers that employ regression analysis.doi:10.1080/03031853.2013.778463Mbatha, C.N.
b. The standard error of the regression (SER) is 624.1. What are the units of measurement for the SER? (Dollars? Years? Or is SER unit free?) c. The regression R is 0.023. What are the units of measurement for the R?? (Dollars? Years? Or is R unit free...
I am usingstreg, dist(ggamma)to estimate an AFT model. How can I obtain the standard error of the regression? I thought this could be done by using_b[_se]. [...] Answer: Rather than_b[_se], type [ln_sig]_b[_cons]
