Chapter 3 Total variation distance between measures

3.2 Total variation and lattice operations 3 The total variation v(µ) is also equal to sup|f |≤1 |µf |, the supremum running over all A-measurable functions f bounded in absolute value by 1. Indeed, |µf |=λ|mf|≤λ|m| if |f |≤1, with equality when f ={m ≥ 0}−{m < 0}. When µ(X) = 0, there are some slight simplifications in the formulae for v(µ).In that case, 0 = λm = λm+ − ...

This shows that f is of bounded variation on [a,b]. Consequently, f0(x) exists for almost every x ∈ [a,b]. 1. Theorem 1.2. ... In this section we show that absolutely continuous functions are precisely those func-tions for which the fundamental theorem of calculus is valid. Theorem 2.1. If f is integrable on [a,b] and Z x a

Review of functional data analysis

form of functions, images and shapes, or more general objects. The atom of functional data is a function, where for each subject in a random sample one or several functions are recorded. While the term \functional data analysis" was coined by Ramsay (1982) and Ramsay & Dalzell (1991), the history of this area is much older and dates back to ...

Brownian motion Xt R - Yale University

L´evy’s martingale characterization of Brownian motion . Suppose {Xt:0≤ t ≤ 1} a martingale with continuous sample paths and X 0 = 0. Suppose also that X2 t −t is a martingale. Then X is a Brownian motion. Heuristics. I’ll give a rough proof for why X 1 is N(0,1) distributed. Let f (x,t) be a smooth function of two arguments, x ∈ R and t ∈ [0,1].Define
