Hierarchical Variation in Cellulose Decomposition Across Southern Ontario Reference Streams
… were studied using a linear mixed effects model (LMEM). A partial least squares (PLS) regression analysis was performed to identify environmental variables associated with decomposition patterns. I found that variance associated with each successive spatial scale was seasonally dependent, and that …

Performance Analysis and Strategic Management of Longitudinal Pavement Markings
… models. A linear mixed effects model (LMEM) was selected as most appropriate for the paint marking retroreflectivity data. LMEMs were established for paint pavement markings based on the data collected in NC. The research outcomes can help transportation agencies have a better …

A methodological framework to assess multi-pollutant personal air quality exposure for improved health associations
… construction of a Linear Mixed Effects Model (LMEM), linking the novel exposure metrics and estimated exposure determinants to a health marker, in this case Peak Expiratory Flow (PEF). While the associations with personal exposure and PEF appear minimal in this study (concerns about the …

Nonparametric testing for random effects in mixed effects models based on the piecewise linear interpolate of the log characteristic function
Traditional linear mixed effect models assume the distributions of the random effects and errors follow normal distribution with mean zero and homoscedastic variance sigma square. This thesis presents a new nonparametric testing approach for normality for the random effects distribution based on …
