Bivariate mixed effects model
WebSpeakers can convey mixed impressions by providing only positive information. As a series of studies shows, when communicators omit information on a salient, relevant dimension of social perception, listeners make negative inferences about the target on that omitted dimension, despite directly receiving only positive information on another dimension … WebAug 17, 2024 · The results showed that the univariate and bivariate mixed models produced very close estimates, especially the fixed effects. Following Fieuws et al. [ 6 ], the correlation between longitudinal MD and VA was summarized in terms of the association between subject-specific evolutions (as measured by random intercepts and slopes) as …
