Fit a precision profile function to describe the imprecision across the measuring interval.
The analysis report updates.
The precision profile show the relationship between the imprecision and the measurand level. The variance function fit describes the relationship as a continuous function.
The variance function describes the relationship between the variance and concentration using a 3-parameter power model typically used for immunoassays.
