6.1.1 Computational Topics

This case study ranges from simple access to data directly from the Internet within R [2], to working with dates, writing fast code, simulating random processes, and “estimating” optimal parameter values for an objective function using a grid search. These include:

Designing, writing and testing small, reusable functions.

Developing efficient code.

Using vectorized operations.

Profiling code and finding the bottlenecks.

Writing and interfacing to C code for speed.

Numerical optimization by grid search.

Dividing data into training and test subsets to determine optimal values.

Simulation of a stochastic process.
