Nettet12. jun. 2024 · Linear mixed-effects models are powerful tools for analysing complex datasets with repeated or clustered observations, a common data structure in ecology and evolution. Mixed-effects models involve complex fitting procedures and make several assumptions, in particular about the distribution of residual and random effects. Nettet9. nov. 2024 · Hyperspectral imagery collected from airborne or satellite sources inevitably suffers from spectral variability, making it difficult for spectral unmixing to accurately …

Nettet24. aug. 2024 · A linear mixture occurs when endmembers are physically mixed or a sample has a composition that can be mathematically considered to be a combination of distinct endmembers with fixed compositions (Weltje 1997).An example of a linear mixture is when red and blue grains are mixed and the result is a mix of individual red … Nettet19. okt. 2024 · Introduction. With mixed models, it is easy to run into data that is larger in size than some more typical data scenarios. Consider a cross-sectional data set with 200 individuals. This is fairly small data. Now, if we observe them each five times, as in a longitudinal setting, we suddenly have 1000 observations.
