The RegressionStatistics property returns a RegressionStatistics object that contains the statistical results of a regression model. When a trend line is not regressive or the solution of a regression does not exist for current data, the RegressionStatistics property returns Nothing (VB) or null (C#).
The following table defines the values used in statistical equations:
| Value | Definition |
|---|---|
| n | Number of points. |
| nt | Number of regression coefficients. |
| x values |  |
| y values |  |
| mean y value |  |
| Fitted y values |  |
The following table displays the name, description, and formula for each member in the RegressionStatistics object:
| Name | Description | Formula | Formula(UseYIntercept=true) |
|---|---|---|---|
| Ssr | The sum of squares due to regression |  |
 |
| Sse | The sum of squares due to error |  |
|
| Rsq | The coefficient of determination (R-squared) |  |
|
| DF | The degrees of freedom |  |
 |
| F | The F-observed(F-statistic) value |  |
