  Workshop on Using Models to Estimate Hog Production
Project Description 
The National Agricultural Statistics Service (NASS) has developed hog models that combine information from surveys, administrative data, and expert opinion to produce the requisite estimates with the goal of replacing current methods that lack transparency and measures of uncertainty. The purpose of the workshop is to discuss the appropriateness of these models and possible improvements or alternative approaches. Issues for discussion at the workshop include the appropriateness of the modeling techniques developed by NASS, the extent to which the model's assumptions can be validated, the robustness of the estimates to a failure of one or more assumptions, and other technical issues of model specification. In addition, the workshop will consider the suitability of the data that feed into the model and the properties of desirable estimates of uncertainty.
