Figure 3.
These Kolmogorov Smirnov (KS) graphs for multiparous (A) and primiparous (B) cows, calculated based upon the individual predicted probabilities of the logistic regression model. The blue lines and red lines indicate the cumulative percentage of sick 1 and healthy 2 cows in each decile, and the yellow lines represent the associated KS statistic (calculated as the difference between the cumulative percentages). 1 Cows that became sick with at least one disease (ketosis, metritis, or mastitis) during the postpartum period. 2 Cows that did not develop ketosis, metritis, or mastitis during the postpartum period.
