Two types of variables are measured and the relationships between the exercise variables and the health variables are of interest.Īs a second example consider variables measured on environmental health and environmental toxins. A number of environmental health variables such as frequencies of sensitive species, species diversity, total biomass, the productivity of the environment, etc. On the other hand, you have variables that attempt to measure overall health, such as blood pressure, cholesterol levels, glucose levels, body mass index, etc. On the one hand, you have variables associated with exercise, observations such as the climbing rate on a stair stepper, how fast you can run a certain distance, the amount of weight lifted on a bench press, the number of push-ups per minute, etc. Canonical correlation analysis explores the relationships between two multivariate sets of variables (vectors), all measured on the same individual.Ĭonsider, as an example, variables related to exercise and health.
