Four independent HDP sampling chains with data from
SomaticCancerAlterations package, saved to mut_count
.
Categories are the 96 base substitution types defined by local trinucleotide
content, and the samples include 100 lung adenocarcinomas, 100 ovarian serous
carcinomas, and 100 skin cutaneous melanomas.
Data is derived from TCGA exome-sequencing studies.
Each sample was assigned to a unique child DP node, with one parent DP node per
cancer type, and one grandparent DP node at the top level.
Each chain initialised with 10 clusters, then run 5000 burn-in iterations
before collecting 50 posterior samples with 200 iterations between each.
