Sentences with phrase «level multilevel models»

Three - level multilevel models (MLM) accounts for within - family dependence by incorporating a unique random effect for each family and adult child, and this variability in random effects is taken into account when estimating SEs.

This paper attempts to evaluate these factors using multilevel modeling methods where the traits of individual research group participants (e.g. gender, ethnicity, discipline area) are modeled within group - level factors (e.g. number of meetings, group size, group composition) as determinants of Working Group - related journal article production.

Effects of Differential Item Discriminations between Individual - Level and Cluster - Level under the Multilevel Item Response Theory Model

Unlike logistic models with only one random error capturing all the variance in the outcome that is unexplained by the model, multilevel models divide the residual variance into three levels, allowing us to capture variation between (i) different parents with the same grandparents; (ii) different grandparent households within the same country, and (iii) different countries.

Multilevel regression models do not provide a direct estimate of first - level variance (parents in our model); for logistic models, the variance at the first level is fixed as the variance of the standard logistic distribution, that is at π 2 / 3, or about 3.29 (Goldstein, Browne, & Rasbash, 2002; Snijders & Bosker, 1999).

Although some research has begun to collect and analyze data at the level of the dyad (Lyons et al., 2007; Pruchno, Wilson - Genderson, & Cartwright, 2008; Wilson - Genderson, Pruchno, & Cartwright, 2008), there remains much to be learned, yet it is clear that advances made regarding multilevel modeling strengthen our ability to conduct such research.

Using publicly available community - level AEDI data, 62, 63 we ran a two - level multilevel logistic regression model for one aggregate developmental outcome measure (ie, risk of developmental vulnerability; figure 3A) and an example simulation (figure 3B) using a total sample of 181 500, with the proportion of Aboriginal children in each LGA derived from ABS estimates.64, 65 Binomial outcome data were simulated assuming a baseline risk of being vulnerable of 21 % and a community - level random effect based on the actual variation in the published data (figure 3A).

We will use two - level multilevel linear and logistic regression models (mothers and babies nested within areas) to compare outcomes between individuals living in an AMIHS area compared with individuals who live in a propensity - matched comparison area, using an intention - to - treat approach.

Because the children are nested within families, we have used multilevel modeling, which takes into account the absence of independence between siblings within families and allows for one than one positive case at the family level.

This paper illustrates a method for operationalizing affect dynamics using a multilevel stochastic differential equation (SDE) model, and examines how those dynamics differ with age and trait - level tendencies to deploy emotion regulation strategies (reappraisal and suppression).

This multilevel AR model enables researchers to estimate the average inertia in the population and to use observed person - level variables as predictors for the inertias, to see which person characteristics are related to regulatory weakness.

Importantly, using the multilevel TAR model, researchers can use person - level variables as predictors both for the inertias, representing the state - dependent regulatory weakness, and for the threshold representing a person's equilibrium.

To test our hypothesis that individuals possessing lower levels of perceived control would report greater increases in depressive symptoms (Time T) following the occurrence of dependent interpersonal stressors (Time T - 1) than individuals possessing higher levels of perceived control (i.e., a diathesis - stress perspective), we utilized idiographic, time lagged, multilevel modeling.

The moderating effect of emotion differentiation on the relation between the specific emotions and intrinsic motivation was tested by means of a series of two - level multilevel regression models using the lme4 package in R.

A multilevel random effects model accounts for the hierarchical structure of the data, in which the effect sizes or study results (the lowest level) are nested within studies (the highest level).
