Help needed - unsure of what test

#1
Hi all,

I am examining fat and muscle cross-sectional area and a number of different variables/parameters. Basically, I want to see what happens with a unit increase of fat (cm2), muscle (cm2) and bmi (continuous), when looking at various parameters: age, sex, bmi categories (Categorical), etc. No adjustments.

I am not sure what the best test to run would be.

Hi,

I think we need clarification when you say "I want to see what happens with a unit increase of fat...". What is the outcome you are trying to measure? What does your sample look like? How was it created? What kind of inferences are you trying to make about a large population? Were these measures taken more than once on each subject? We need a lot more to understand your problem.
