First, it is discussed that theTaylor series expansion approach gives us thebiasedestimators. Next, a Monte-Carlo simulation filter isproposed, where each expectation of the nonlinear functionsis evaluated generating random draws. It is shown fromMonte-Carlo experiments that the Monte-Carlo simulationfilter yields the unbiased but inefficient estimator.Anotherapproach to the nonlinear filtering problem is toapproximate the underlyingdensity functions of the statevector. In this monograph, a nonlinear and nonnormal filteris proposed by utilizing Monte-Carlo integration, in which arecursive algorithm of the weighting functions is derived.The densityapproximation approach gives us anasymptotically unbiased estimator. Moreover, in terms ofprogramming and computational time, the nonlinear filterusing Monte-Carlo integration can be easily extended tohigher dimensional cases, compared with Kitagawa‘s nonlinearfilter using numericalinteg | | 出版日期 | Book 19931st edition | | 關(guān)鍵詞 | Kalman Filter; Nichtlineare Filter; Nonlineare Filter; Normal; Transit; econometrics; estimator; filtering; | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-662-22237-9 | | isbn_ebook | 978-3-662-22237-9Series ISSN 0075-8442 Series E-ISSN 2196-9957 | | issn_series | 0075-8442 | | copyright | Springer-Verlag Berlin Heidelberg 1993 |
