Analysis of change in discrete variables
Versucht wird, eine Annäherung an die Analyse der Veränderung von diskreten Variablen zu leisten. Als methodisches Modell wird die Marcov-Kette benutzt, die einen brauchbaren Rahmen für die Analyse abgibt und in Zusammenhang mit ereignisgeschichtlichen Daten die Veränderungsraten bestimmbar macht. Kritik an der Brauchbarkeit der Marcov-Kette wird vom Autor zurückgewiesen. Er zeigt, daß dieses Modell auch den ad hoc statistischen Techniken Überlegen ist, weil diese ereignisgeschichtliche Daten von Veränderung nicht adäquat in die Bestimmung von historischen Veränderungen einbeziehen. Und gerade ereignisgeschichtliche Daten erlauben die direkte Analyse von Veränderungen, und deshalb ist hier ein entsprechendes methodisches Modell notwendig. (BG

Shared heritability and functional enrichment across six solid cancers
Correction: Nature Communications 10 (2019): art. 4386 DOI: 10.1038/s41467-019-12095-8Quantifying the genetic correlation between cancers can provide important insights into the mechanisms driving cancer etiology. Using genome-wide association study summary statistics across six cancer types based on a total of 296,215 cases and 301,319 controls of European ancestry, here we estimate the pair-wise genetic correlations between breast, colorectal, head/neck, lung, ovary and prostate cancer, and between cancers and 38 other diseases. We observed statistically significant genetic correlations between lung and head/neck cancer (r(g) = 0.57, p = 4.6 x 10(-8)), breast and ovarian cancer (r(g) = 0.24, p = 7 x 10(-5)), breast and lung cancer (r(g) = 0.18, p = 1.5 x 10(-6)) and breast and colorectal cancer (r(g) = 0.15, p = 1.1 x 10(-4)). We also found that multiple cancers are genetically correlated with non-cancer traits including smoking, psychiatric diseases and metabolic characteristics. Functional enrichment analysis revealed a significant excess contribution of conserved and regulatory regions to cancer heritability. Our comprehensive analysis of cross-cancer heritability suggests that solid tumors arising across tissues share in part a common germline genetic basis.Peer reviewe
