Airborne laser scanning (ALS) based height and intensity information was exploited for the vertical stratification of vegetation layers in
a multilayered Mediterranean ecosystem. A new methodol...
Identifiability and Estimation of Causal Effects by Principal Stratification with Outcomes Truncated by Death
Causal inference Identifiability Principal Stratification Truncated by Death
2016/1/19
In medical studies, there are many situations where the final outcomes are truncated by death, in which patients die before outcomes of interest are measured. In this paper we consider identifiability...
STRATIFICATION:A PROBLEM IN RANGELAND MONITORING
Rangeland monitoring Stratification Remote sensing Pixel and object-based image analysis
2015/8/19
Resource stratification for ground-based and remotely-sensed methods of rangeland assessment is essential for locating appropriate sampling sites. This is particularly the case when site comparisons a...
