On starr and vardi's estimates of the number of transmission sources
Peter M. Hall · Journal of Applied Probability · 1982
We propose an estimator for the number of sources, N, which transmit signals according to a Poisson process with a common rate μ. This estimation problem was originated by Starr and pursued by Vardi. Our procedure is a ‘double sampling’ one and has the advantage that it can be used when μ is unknown.
