Childhood Cancer Spatial Clusters Benchmarking Data - Data in Brief Manuscript, Schündeln et a. 2020

Incidence of newly diagnosed childhood cancer (140/1,000,000 children under 15 years) and nephroblastoma (7/1,000,000) was simulated. Clusters of defined size (1 to 50) were randomly assembled on the district level in Germany. Each cluster was simulated with ten different relative risk levels (1 to 100). For each combination 2000 iterations were done. Simulated data was then analysed by three local clustering tests: Besag-Newell (BN) method, spatial scan statistic (SSS) and Bayesian Besag-York-Mollié with Integrated Nested Laplace Approximation approach (BYM). RAW DATA: The simulated raw data is reported in the Rdata files: "AllMalignancies.Rdata" and " NephroblastomaSimulation.Rdata". These files contain 6 lists for the different cluster sizes ("Cluster Size X"). Within each of these lists 2000 simulations for clusters in 10 different risk levels ("RR Y Cluster") and the corresponding simulated cases for each of the respective scenario ("RR Y SimCases") are found. In addition, each file contains the population of children under 15 years for each district (“District Population”) and the expected cases for the entities, all cancer or nephroblastoma, (“Expected Cases”) per district. The adjacency matrix for the 402 German districts is added as a separate Rdata file.
