Logistic regression model is used for estimating the unknown population size using multiple data sources. The model was introduced in the study of Alho (1990) and two data sources with binary indication of a case are used.

Newton-Raphson method used in this algorithm can be
replaced by optim()
.
This program is the initial implementation (without any code optimization).
