Estimate the recurrence risk ratio of familial recurrence risk divided by population prevalence, based on results returned from fam.recrisk
1 | recrisk.ratio(fit)
|
fit |
list returned from fam.recrisk |
The recurrence risk is based on a truncated binomial density, and the prevalence is the frequency of disease in the sample. If the sample of families in not a random sample from a population, the prevalence will be biased, and merely represent the frequency of disease in the sample.
A list with the following values
rr |
ratio of recurrence risk divided by population prevalence |
var.rr |
variance of rr |
