Test: Parameter/property point estimate
Add one or several tests for single parameters to your assay. These tests are for assay elements that have a multi-dose preparation scheme. To add the tests as assay suitability tests, add them as children of the Assay suitability tests element. To add the tests as sample suitability tests, add them as children of the Sample suitability tests element.
Important: Test definitions are ignored without notification if the parameter you select results in invalid test definitions (for example, if a test cannot be performed for the model you use).
The following table lists all available tests and indicates which models they support:
| Point estimate test on the: | Linear model | 4-parameter logistic model | 5-parameter logistic model | 3-parameter logistic model with fixed lower or upper asymptote |
| A upper asymptote (nonlinear models) | no | yes | yes | with fixed Lower asymptote |
| B parameter (nonlinear models) | no | yes | yes | yes |
| C parameter (nonlinear models) | no | yes | yes | yes |
| Lower asymptote (D) (nonlinear models) | no | yes | yes | with fixed Upper asymptote |
| Asymmetry parameter (G) (nonlinear models) | no | no | yes | no |
| Intercept (linear models) | yes | no | no | no |
| Slope (linear models) | yes | no | no | no |
| Slope (nonlinear models) | no | yes | yes | with fixed Upper asymptote |
| Difference of asymptotes (A - D) (nonlinear models) | no | yes | yes | no |
| Ratio of asymptotes (A / D) (nonlinear models) | no | yes | yes | no |
This element has the following attributes:
| Data type | Multiplicity | Usage | Default value |
| Node | 0...unbounded | optional | none |
