The Time of the Insult/Triggering Event in Primary Osteosarcoma and Ewing’s Sarcoma of Bone as Determined by Incubation Period Modeling and Age Distribution of Such Malignancies

Figure 3

Single asymmetric peak distribution function fits of Ewing’s sarcoma of bone with the Pearson IV distribution (a) and the log normal distribution (b). Note that the log normal distribution poorly fits the younger ages, making it difficult to determine .
