Exercise 1

Exercise 1: Effect of non-process error (it helps here to think of it as measurement error)

Type 'Lab1' at matlab prompt.
When asked for data code, type 3 (this is a White-capped albatross time series).

Param set 1: set mu = 0; s2p = 0.01; s2np = 0.1
Param set 2: set mu = 0; s2p = 0.01; s2np = 0.01
Param set 3: set mu = 0; s2p = 0.01; s2np = 0.001

Questions for Exercise 1:

1. Why is the fit closer to the observations as the npe parameter is lowered?

2. The ML fit hardly seems to fit the data at all. What's going on there?
