Graphical visualisation of the FOD-M model assumptions. A An example set of T (blue), O (pink) and R (brown) distributions. B The determined RD value for the example in (A) is 0.633, as shown on the axis. This value is calculated to express the difference expressed by DKL(O|T) and DKL(O|R) according to Eq. 4. C Determination of optimum value for K – the minimum DKL value for different K values results in best fit. The K = 0.3 appears to be the optimal one for presented example. D The juxtaposition of the T (blue), O (pink) and M (cyan) distributions for K = 0.3 illustrates the interpretation of the M distribution, which most closely replicates the O distribution in the example in question. Additional (thin lines) represent the M distributions for K = 0.1 (thin line – pink) and M distribution for K = 0.5 (thin line – blue). The comparison of M distributions visualises the best fit for M distribution for K = 0.3
