Exercises and hand-ins 2007

TMS165/MSN600 Stochastic Calculus, Part I, 5 credits (Stokastisk analys, del I, 5 poäng)



Hand-ins

The hand-in exercises are, respectively, due to fridays during the remainings of this course. Students are recomended to hand in the assignments two and two. They may be handed in during class, or to me at room MVL:3070. Solutions should be well motivated, clear and easy to read. Especially should simulations be explained carefully. The grades for this course will be based on your solutions of the hand-in problems.

Grading: To pass this course, we will implement the following algorithm:
  function G=pass(X)            % G=1 means pass, G=0 fail, X vector with hand-in scores
  M=[M1, M2, M3, M4, M5, M6];   % maximum on each hand-in
  S=sum(X);                     % total points
  G=1;
  for i=1:6
    if X(i)<0.3*M(i)
      G=0;
    end
  end
  if S< 0.5*sum(M)
     G=0;
  end
That is, 50% of the total score must be achived, and at least 30% on each hand-in. Note: Simulations are a part of this course that cannot be neglected. Understanding this algorithm is a good start!

Deadline: All hand-ins must be handed in by October 26! Students who fail to do so, we cannot promise when their grades will be available for registration in the Ladok-system.

No 1. Due September 14.
No 2. Due September 21.
No 3. Due October 5.
No 4. Due October 12. Simulation to problem 2 may look like this. Also, I have one hand-in 4 without namo on. Please come by and identify it if you haven't had yours back! (good grade)
No 5. Due October 19.
No 6. Due October 26.
