First, we employ a VAR model, which allows correlations between the three different weather variables to be captured.
(The results for all daughters, using a regression model which includes correlations between sisters, were similar to the results for the oldest daughters).
Informative censoring can be explicitly modeled by fitting a bivariate survival model in which correlation between time until hospitalization and time until death is modeled using a resident-specific latent variable (Lancaster and Intrator 1998; Fleming and Lin 2000; Ghosh and Lin 2003;).
Data from measurements on >30 cells were pooled and fit globally (i.e., simultaneously) to a two-component diffusion model, which gave correlation times of τ = 1.34 ms and τ = 18.1 ms. These correlation times correspond to apparent diffusion coefficients (Dapp) of 19.6 μm/s and 1.43 μm/s (Table 1).
In this article, the SA problem in OFDMA networks has been studied in a realistic channel model which considers correlation between adjacent subcarriers.
We test our hypotheses in the context of a trivariate probit model which allows correlation in the errors among three choices.
This was analyzed with the general linear mixed model, which takes correlation within subjects into account.
Judd et al. conducted the first experimental study in 1995, in a reperfused canine infarct model, which showed correlation of CMR findings with pathology, by thioflavin-S staining [ 14].
Constructs are denoted by variables in a model that predicts which correlations would be observed among the indications of different measures if they are indeed measures of the same attribute.
Table 2 shows the model fitting results of the social homogamy (SH) model (model SH-1: χ(6) = 23.12, p < .01), and the phenotypic assortment (PA) model (model PA-1: χ(6) = 21.58, p < .01) compared to the constrained saturated model (i.e., model S-2, in which correlations for all relations through DZ and sibling pairs were constrained to be equal).
