Among the existing methods for the expression uncertainty in measurement, the most common is the classical GUM method. The formula for the sum standard uncertainty of the output value includes the values of partial derivatives (sensitivity coefficients), the determination of which in the case of complex model equations, often encountered in biological measurements, causes certain difficulties.
