Use the same random numbers when possible...so that each replication
uses the same random numbers - which method is better, and how
often.

Variables, constraints and objective function for optimization for
GARCH
Give this one a try later!
variables = a0,a1,...am (coefficients)
constraints = none
objective function = minimize prediction error
, variables = coordinates for cluster centers, and binary variables for whether each
data point is part of each cluster
constraints = each data points must be assigned to exactly 1 cluster
objective function = minimize the sum of distances from each data point to its
cluster center
variables = omega, Beta i, gamma i
constraints = none
objective function = minimize the prediction error
(standard regression, w/ 1 constraint added)
variables = a0,a1,...am (coefficients)
constraints = restrict the sum of the variables
objective function = minimize the squared error in the model estimates

At each step, it does the one thing that looks best
without taking future options into consideration. Good for initial
analysis
1. Forward selection
2. Backwards elimination
3. Stepwise regression
