Estimate familial recurrence risk, assuming there is a single identified proband in a family
1 | recrisk.single.ascertain(s, a)
|
s |
vector of sizes of families |
a |
vector of number of affected members |
When affected subjects (i.e., probands) attend a clinic independent of their family size and independent of their family history, and if the family history provided by probands is complete (i.e., reporting of family history does not depend on the number of affected members), then we can view the probands and their families as sampled under complete ascertainment. This function estimates the disease recurrence risk when there is a single identified proband per family.
