# If I have a random variable $X$ that follows a distribution identically (but not independently), $X \overset{id}{\sim} F$, why is this non-parametric?

Suppose I have a random variable $$X$$ that follows a distribution identically (but not independently), $$X \overset{id}{\sim} F$$. This is usually meant to say that $$X$$ has a non-parametric specification. I am wondering why $$X$$ is non-parametrically specified in this case. Could anyone give some pointers?
