| Tiivistelmä: | A hierarchical model is developed to account for selection biases that result from processes in which events have a fixed probability of being sampled, but individuals in the population generate events at varying rates. It is shown that inferences about the population parameters from such unrepresentative samples are not only possible but can be statistically powerful, provided the selection biases are adequately controlled for and the specification of the model is appropriate. |
