Basically, when you look at different types of cells, such as fibroblasts, which form connective tissue, or epithelial cells, from saliva, you see general correlations within a person. (scientificamerican.com)
In general these correlations for the model runs are high and lowered from higher values primarily by various segments of consecutive years having either an offset or a different slope with the segments individually having high correlations. (climateaudit.org)
Similarly, removal of the relationship - general correlation also reduced the model fit significantly, Δχ2 (1) = 20.3, p <.001. (interpersona.psychopen.eu)
