NB! Studentweb will open for applications from NMBU students by the middle of January 2019.

The course is of 5 ECTS, and is organised by Prof. Terje Gobakken, Norwegian University of Life Sciences.

Course Description
In sample surveys, there are two main inferential approaches: the design-based and model-based. The probability sampling theory is part of the former, regression analysis and econometrics provide estimators within the latter inferential mode. Hybrid inference was developed by Nordic scientists to satisfy needs in surveys of natural resources in which auxiliary data from remote sensing play an important role. The new hybrid inference combines properties of the design- and model-based approaches and accounts for uncertainties due to both design and model. The course will provide a general and practical view, as well as a deeper scientific understanding of the new hybrid inferential approach.

The course will focus on the hybrid inferential approach for surveying discrete and continuous natural populations in the presence of auxiliary data. It includes elements from sampling survey theory, such as general sampling concept for discrete and continuous populations, sampling with fixed area plots, relascope sampling, stratified sampling and cluster sampling; as well as elements from regression analysis, such as ordinary least squares regression, generalized least squares regression and maximum likelihood estimators.
