expected.nb {emon} | R Documentation |
The function is used to obtain the method of moments estimator within the function GVFCMOM
.
Calculates the expected value of the Visual Fast Count method.
The function assumes that the count per segment is Negative Binomial with mean m/s
and size k
,
and that segment counts are independent. The expected value is also a function of the number of positives
d
before segment counting is stopped.
