Nonparametric factor analysis of time series

Rodríguez Poo, Juan Manuel; Linton, Oliver - 1998

We introduce a nonparametric smoothing procedure for nonparametric factor analaysis of multivariate time series. The asymptotic properties of the proposed procedures are derived. We present an application based on the residuals from the Fair macromodel. -- Factor Analysis ; Time Series ; Kernel...

A nonparametric test for the stationary density

Neumann, Michael H.; Paparoditis, Efstathios - 1998

We propose a nonparametric test for checking parametric hypotheses about the stationary density of weakly dependent observations. The test statistic is based on the L2-distance between a nonparametric and a smoothed version of a parametric estimate of the stationary density. It can be shown that...

Flexible stochastic volatility structures for high frequency financial data

Feldmann, David; Härdle, Wolfgang; Hafner, Christian M.; … - 1998

Stochastic Volatility (SV) models are widely used in financial applications. To decide whether standard parametric restrictions are justified for a given dataset, a statistical test is required. In this paper, we develop such a test based on the linear state space representation. We provide a...

A mixed user interface for a statistical system

Yamamoto, Yoshikazu; Nakano, Junji; Fujiwara, Takeshi; … - 2001

A user interface is one of the most important factor's for deciding the usefulness of a statistical system. Nowadays, a graphical user interface (GUI) is popular because it is easy and intuitive to use. A character user interface (CUI) is, however, still important for using full abilities of the...
