- Hence both (A) and (B) imply (3) which is the affirmation of the theorem. QED

- Proof
- Slide 14
- Slide 15
- Having proved the assertion of this theorem for finite- dimensional distributions and having proved the tightness we have proved the theorem. QED

- Unit Dimension {-1,+1} N=20 N=60 N=1000
- Slide 18
- Application of Donskers Theorem More important than this qualitative interpretation is the use of Donsker's theorem to prove limit theorems for various functions of the partial sums
