Multivariate Linear Models
For example, we may have (i) measurements of d = 5 air pollutants (CO, NO, etc.) on n = 42 widely-separated days, (ii) d test scores for n different students, (iii) best results for d Olympic events for teams from n different countries, or (iv) d different physical measurements for n individuals (human or animal) that we are trying to classify. In each case, the i row corresponds to the i multi...
متن کاملMultivariate Linear Path Models
Path analysis is useful to explain the interrelationships among sets of observed variables in a causal chain. However, path analysis has been underutilized in health science and epidemiology research, because of its restrictive requirement of a complete causal ordering of variables. In order to solve this problem, we suggest the use of multivariate path models and derive a multivariate ”Calculu...
متن کاملMultivariate linear mixed models for multiple outcomes.
We propose a multivariate linear mixed (MLMM) for the analysis of multiple outcomes, which generalizes the latent variable model of Sammel and Ryan. The proposed model assumes a flexible correlation structure among the multiple outcomes, and allows a global test of the impact of exposure across outcomes. In contrast to the Sammel-Ryan model, the MLMM separates the mean and correlation parameter...
متن کاملHE Plots for Multivariate Linear Models
Multivariate analysis of variance (MANOVA) extends the ideas and methods of univariate ANOVA in simple and straightforward ways. But the familiar graphical methods typically used for univariate ANOVA are inadequate for showing how measures in a multivariate response vary with each other, and how their means vary with explanatory factors. Similarly, the graphical methods commonly used in multipl...
متن کاملUsing multivariate generalized linear latent variable models to measure the difference in event count for stranded marine animals
BACKGROUND AND OBJECTIVES: The classification of marine animals as protected species makes data and information on them to be very important. Therefore, this led to the need to retrieve and understand the data on the event counts for stranded marine animals based on location emergence, number of individuals, behavior, and threats to their presence. Whales are g...
