Quiz #5

Several questions throughout class.

Arg max/min



Fitting a model to data, cont'd

Example: approximately exponential separation of trajectories in mayfly model

How to define and calculate the "best" straight line? Last time, several measures of badness were suggested.

Exploration: Let's compare how they work.

Pointwise error ei = αxi + β − yi

Analytical solution for choice E = ni = 1e2i

argmin(α, β) ∈ ℝ2
