Web25 Sep 2024 · The calculation of ddCt involves subtraction of the dCt calibrator value. This is subtraction of an arbitrary constant, so the standard deviation of the ddCt value is the same as the standard deviation of the dCt value. This makes no sense to me. How is the calibrator value an "arbitrary constant", when it's measured and has uncertainty?

WebThe errors in x are assumed to be distributed randomly. In finding a representation of the average errors, the positive and negative errors cancel upon summation. To avoid cancellation of errors, Eq. A1.2 is recast in terms of the variance, for the same reason that the standard deviation is also based on a sum of squared errors.
