Test: Maximal sequence step CV (%)

Add one or several tests for the maximal percentual coefficient of variation (CV) of sequence steps to your assay.

The percentual CV is calculated as follows:

C V = | Standard Deviation Mean | ⋅ 100
Note: Technical and statistical outliers are excluded from the calculation of the CV. The test returns an 'NC' (not calculated) if one or more sequence steps have only one observation.

To pass the test, all sequence step CVs have to be less than or equal to the upper margin set in the test definition.

Supported models

Linear parallel-line, 4-parameter logistic, 5-parameter logistic, 3-parameter logistic with fixed lower asymptote, 3-parameter logistic with fixed upper asymptote, Slope ratio

Scope of the test

  • Standard only: Runs the test for the Standard sample.
  • Test samples only: Runs the test for every Test sample.
  • Control samples only: Runs the test for every Control sample.
  • Control lines only: Runs the test for every Control line.
  • All assay elements: Runs the test for every assay element.

This element has the following attributes:

Data type Multiplicity Usage Default value
Node 0...unbounded optional none
