Notes. Each row corresponds to a DTD while each vertical block refers to a particular CSFR. Columns in each block contain the χ² value per degree of freedom (left column), the optimal fraction ${\hat{A}}_{Ia}$ $\hat{A}_{\mathrm{Ia}}$ (middle column) and the 1 − p value of the χ²-test (right column). For each CSFR, p values lower than 0.05 (i.e, 1 − p> 0.95) are highlighted in bold.
