The objective of population modeling is to study the impact of tobacco products on the population as whole. Input parameters include demographic information, tobacco use transition probability and mortality and/or morbidity. The input parameters are typically derived from population-level sources (e.g., census data or other population-level surveys). However, depending on the objective, other sources of data may be used. When using these other sources, steps should be taken to ensure they are representative of the population.
In this section, the inputs to these models and how they are represented in CDISC standards for submission to a regulatory authority are discussed. Model outputs are not currently covered in this section but may be covered in a later release. However, regulatory agencies expect full information to replicate the analysis based in the outputs.
