| Outline of Final Research Achievements |
We proposed a new test statistic based on discrete Fourier transformas of spatio-temporal data for parametrics models of stationary random fields.
It is constructed by smoothing periodograms of different frequencies by a kernel function. Under the null hypothesis in that a supposed parametric model is true, the test statistic has simple asymptotic expectation and variance, and hence it can be implemented easily to analyze acutual data. Furthermore it is expected that it is asymptotically normally distributed.
