The steps followed include model specification, model estimation, and hypothesis testing in general linear model setting. Among these steps, estimation of model parameters such as the main effect least squares means and contrasts were among the most challenging for students. Since no unique solution ...
Environmental data were obtained from the CIELO climatic model and using GIS. The explanatory value of environmental variables on a small-scale gradient of endemic and exotic arthropod species richness was examined with generalized linear models (GLMs). In addition, the impact of both endemic and ...
In addition, the associations between engagement in the GRTQ items and other potential explanatory variables, such as age, gender, socioeconomic and other demographic characteristics, were also explored using generalized linear models (GLMs). Results...
presented (Klienbaum, 1994). The results go beyond the statistical test of significance and highlight the important role that effect size (odds ratio, log odds ratio, relative risk or probability ratio) and confidence interval (asymptotic standard error; ASE) have in the general linear model ...
2.1. Model Previously, a general linear model in the Fourier, domain to model single or univariate fMRI time series was presented [33–35]. In this model, a simple scalar quantity,s(t), represented the fMRI time series. In order to model a repeated measures experimental design with multiple...
A method is presented to assess the extent to which a functional activation can reliably be explained by underlying anatomical differences, and simultaneously, to assess the component of the functional activation which cannot be attributed to anatomical difference and thus is likely due to functional ...
P values (triglycerides: P < .01 for ischemic stroke vs controls in men and P < .05 in women; remnant cholesterol: P < .01 for ischemic stroke vs controls in men and P < .05 in women) are from general linear models adjusting for age, total cholesterol level, alcohol consumption, ...
Importantly, for the purpose of our neural analysis, both ES and OE can be constructed by subtracting/adding CE and GE on the contrast-level within a single general linear model. We repeated an analogous, control analysis of RTs—an index of motivational change in relation to response vigor ...

For a multiple linear model, we derive the estimators analytically in Sect. 3. The use of imprecise probabilities will increase the overall variation of the estimator, and moreover, the effect of the variance reduction will decrease. As we will demonstrate, however, variance reduction will still...
