F-test (hypothesis test)

Add one or several F-tests to your assay. 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.

F-tests are calculated for every individual assay element (sample) that has a multi-dose preparation scheme. The F-ratios tested are provided in the ANOVA tables.

Select the F-test you want to use from the Type drop-down list. The following options are available:

  • Lack of fit
  • Model

Supported models

All

F-values

F-values are calculated as follows:

Lack of fit

Tests for the significance of the non-linearity term. The F-value is calculated as follows:

F = MSLackOfFit / MSPureError.

Where: MS is the mean squared error.

The test is passed if F ≤ Fcritical.

Model

Tests for the significance of the regression term. The F-value is calculated as follows:

F = MSModel / MSResidualError.

Where: MS is the mean squared error.

The test is passed if F ≥ Fcritical.
