Query: Visualisation of financial time series by linear principal component
  analysis and nonlinear principal component analysis   In this dissertation, the main goal is visualisation of financial time
series. We expect that visualisation of financial time series will be a useful
auxiliary for technical analysis. Firstly, we review the technical analysis
methods and test our trading rules, which are built by the essential concepts
of technical analysis. Next, we compare the quality of linear principal
component analysis and nonlinear principal component analysis in financial
market visualisation. We compare different methods of data preprocessing for
visualisation purposes. Using visualisation, we demonstrate the difference
between normal and crisis time period. Thus, the visualisation of financial
market can be a tool to support technical analysis.
