Select menu Stats | Regression Analysis | Validation of Predictions
Fits linear regression models to validate predictions, for example from a deterministic model, against observed data.
- After you have imported your data, from the menu select
Stats | Regression Analysis | Validation of Predictions.
- Fill in the fields as required then click Run.
There are 4 models fitted in the analysis.
|Null model||The null model with the slope set to 1 and constant/intercept set to 0|
|Slope = 1||The model with the slope set to 1 and constant/intercept estimated from the data|
|Constant = 0||The model with the constant/intercept set to 0 and slope estimated from the data|
|Full model||The full model with the slope and constant/intercept estimated from the data|
The adequacy of the these models are tested, and the significances of the departures from a slope of 1 and constant of 0 are tested.
This lists data structures appropriate to the current input field. The contents will change as you move from one field to the next. Double-click a name to copy it to the current input field or type the name.
