CAP-2EXP pattern, normalized residuals. (a) Test for the additive () noise model. (b) Test for Poissonian noise (). (c) Test for multiplicative noise (). The homoscedasticity of the residuals on (c) indicates that the noise is multiplicative, confirming the noise model used in simulated generation of the data (3).
