The course concentrates on nonparametric estimation of
regression and classification functions.
Regression and classification functions can be used to predict
future observations when noisy historical data is available.
Nonparametric techniques can be used when a large amount of
observations is available and one is not willing to assume strict
parametric form for the estimated functions.
The course
covers methods
to select portfolios
and
to evaluate option contracts
making realistic assumptions of the market behaviour.
The covered methods include:
- Linear methods, generalized linear models
- Local averaging: kernel and nearest neigborhood regression
- Empirical risk minimization
- Single index models
- Partially linear methods
- Support vector machines
- Aggregation
- Tree based methods
The R-package "finatool" implements
the methods that are covered in the lecture series.
