As earlier stated, the multicollinearity influences the performance of the maximum likelihood estimator (MLE) in both the linear regression models and the Poisson regression models (PRM). The ridge regression and Liu estimator at a different time were harmonized to the PRM to solve multicollinearity....

Association time, chromosome size, centromere, and telomere effects were binned in 20-kb windows and used as explanatory variables to model DSB-protein dissociation time (a) or ChIP density at 6 h (d) by multiple linear regression. Association time was excluded in d. Each point compares the ...
Linear regression models were used to investigate the relationship between SEP and CRP concentration at baseline. We defined a minimally adjusted model controlling for age and sex (sex only for the NCDS where participants are the same age) (Model 1), then we further adjusted for each potential ...
