For combined cancers, the different socioeconomic indicators retain their significance in models including the other socioeconomic indicators (Model 2), with the sole exception of Social Class in the female model.
Associations between symmetry and trait size are more consistent with indicator models than an arbitrary process [8], [13].
The effects of all variables diminished in the multi-indicator model (i.e. with adjustment for all indicators of marginalization), though most remained statistically significant with odds ratios in the range of 1.30 to 2.81, among those which remained statistically significant.
Further analyses were conducted using DCCT/EDIC M1 including adjustment for PCs, and testing for deviation from an additive genetic model by including a heterozygous indicator to a model with rs1495741 coded additively.
Qualitative matching is incorporated into the model with indicator variables, i.e., some is an indicator variable for respondents in a "somewhat related" job, while close is an indicator variable for respondents in a "closely related" job.
Owing to computational limitations, models of indicator variability (both fixed and random effects) failed to converge, hence we used a three level model with indicator observations nested within practices and practices nested within primary care trusts.
( underline{D}_{r,l} ) is an important indicator coordinating the upper model with the lower model.
If the continuous model was not significantly different from the model with indicator variables (p ≥0.05), the linearity hypothesis was accepted.
The number of correct turns, scored over five trials, was considered as count data for each time point during the experiment, with a random-intercept multilevel Poisson model with indicator variables fitted for each time point.
We also fitted a model with indicator variables for the deciles of O3[24hr] exposure averaged over the entire pregnancy and presented the difference in birth weight associated with each decile of O3[24hr] exposure relative to the lowest decile.
