By adding an estimable effect, linked to the categories of event but not confounded with it, representing a summary of possible comparisons between categories of event, the phenotype is correctly modeled.
At the end of the 400 generations of simulation, the allelic effects were standardised so that the total genetic variance was 1. Phenotypes for the G2t individuals were obtained by adding an environmental effect sampled from N 0,0.25) to their genetic value.
Therapist effects: these will be explored by adding a random effect term (to represent the treating therapist) to the main treatment models.
The fixed effects analysis (linear regression model) will also be generalised by adding a random effect for recruiting centre to allow for possible heterogeneity in patient outcomes due more generally to the recruiting centre.
The regression models attempt to account for extra variation, caused by using imputed values, by adding a random effect in the regression model which estimated the outcome measure.
Second, imprinted effects of genes can be detected in a quantitative genetic framework by adding a gametic effect to the model (Tier and Solkner, 1993; de Koning et al., 2002).
This contributes to college tuition increasing faster than inflation by adding a multiplier effect.
Finally, we extended the covariates model by adding a random effect representing a regression on the pedigree, and this model was denoted as pedigree.
However, when we further tested a model that included correlations among pipelines by adding a random effect, with the stringent threshold we obtained maximum sensitivity and specificity by using lumi QN + BMQ or lumi BMIQ.
This may be taken into account by adding a random effect within each group, combining thus a categorical variable (i.e., label g of the group) with intra-group heterogeneity.
