A correlation coefficient close to unity (r = 1) is considered by some authors’ sufficient evidence to conclude that the calibration curve is linear. However, r is not an appropriate measure for the linearity.

Consider, in an affine transformation we could … Nettetlinearity: each predictor is related linearly to \(e^B\) (the odds ratio). Assumption 4 is somewhat disputable and omitted by many textbooks 1,6. It can be evaluated with the Box-Tidwell test as discussed by Field 4. This basically comes down to testing if there's any interaction effects between each predictor and its natural logarithm or \(LN\).

NettetThe correlation ratio is equal to the square root of the sum of squares for an interval type of variable, which has been grouped as between type variables divided by the total sum of squares. The value of the numerator and the denominator play an important role in defining the extent of linearity or non-linearity among the variables.

The assumption that your target probability can be modelled as a linear combination of log-odds ratios scaled by your inputs is equivalent to assuming that it is a combination of independent pieces of Bernoulli evidence.
