For example, in toxicology, exposed dams who are more sensitive to a toxin may tend to have smaller litters and offspring with greater probability of deformation than less sensitive dams, so that Y (pup being deformed) and N (litter size) are dependent given X (exposure of dam).
For example, in longitudinal analysis, scores are nested within students, and students are usually nested within classes.
For example, in long term longitudinal studies, low Conscientiousness in childhood predicts cigarette smoking in adulthood [ 48, 49].
For example, a longitudinal study found ankle proprioception could predict ankle injuries in college basketball players [ 39].
For example, in eight-month-old heifers separated for three weeks from their dams, the pattern of social interactions with the dam was minimally affected after reunion, even though nursing had ceased [ 43].
For example 'In the dark'.
A final example is dropouts in a longitudinal study, where participants do not return for future testing sessions.
For example, variations in licking by dams results in alterations in CNS regulation of the hypothalamic-pituitary-adrenal axis via alterations in hippocampal glucocorticoid receptor expression levels [ 73].
For example, a dam does not change health directly; rather, a dam causes changes in water flow, which may affect mosquito habitat, which in turn can affect transmission potential of malaria.
It follows them for five years and it's a spectacular example of a longitudinal documentary where you get to glimpse the machinery of life.
