Fig. 2From: Process-based approach to modeling recurrent-event data explicated on the basis of occurrences of tooth losses in two different prosthetic treatment conceptsIndividual and sample cumulative history functions for the SJ data set containing both treatment groups. Gray lines: Individual cumulative event counts (histories) with Ni(t) for i=1,…,149 (patient ID). All curves Ni(t) have a small vertical offset with respect to Ni−1(t) so that overlays, particularly at zero, become visible. Red curve: CSMF according to Eq. 3. Green curve: CSVF according to Eq. 4.
