A preliminary study of the statistical analyses and sampling strategies associated with the integration of remote sensing capabilities into the current agricultural crop forecasting system [PDF]

open access: yes
Extending the crop survey application of remote sensing from small experimental regions to state and national levels requires that a sample of agricultural fields be chosen for remote sensing of crop acreage, and that a statistical estimate be formulated

Aggregate administrative data and estimation from nonprobability samples

open access: yes, 2021
In the last two decades survey research has faced two main challenges: the spread of online research using non-probability samples and the general drop of response rates. In this scenario complex adjustments are needed to preserve the inference process.

Estimation methods for data from nonprobability samples

open access: yes, 2020
The main goal of the present dissertation is to evaluate the asymptotic behaviour of estimators for data from nonprobability samples. In this context some target population units do not have positive inclusion probabilities, which means that estimation is affected by biases associated with under-coverage or self-selection errors.
