Web Science/Part2: Emerging Web Properties/Advanced statistical descriptive models for the Web/Fitting a curve on a log log plot

Know the axioms for a distance measure and how they relate to norms.
Know at least two distance measures on functions spaces.
Understand why changing to the CDF makes sense when looking at distance between functions.
Understand the principle of the Kolomogorov-Smirnov test for fitting curves

2 supose we have $f:[0,6]\longrightarrow \mathbb {R}$ with $f(x)=x$ . What is the value of $||f(x)||_{\infty }$

3 supose we have $f:[0,6]\longrightarrow \mathbb {R}$ with $f(x)=x$ . What is the value of $||f(x)||_{1}$

	It is often used to fit a curve
	It must be used to fit a curve
	it uses the uniform norm of the curve and observed data
	it uses the uniform norm on the CDF of the curve and the CDF of the observed data
	it uses the L1-norm on the CDF of the curve and the CDF of the observed data
