基于半参数模型的水位数据预处理方法研究
Research on Tidal Data Pre-processing Method Based on Semi-parametric Model
摘要
Abstract
To solve the problem that observation data may exist fluctuation because of weather influence and water vibration,the model of semi-parametric is used to smoothen the water level observation registered by pressure-type tide gauge.And some data experiments are performed to evaluate the fitting precision of this method.The results of experiments show that the model of semi-parametric is effective to remove system error and make hydrograph smoother and is more reasonable.The conclusion is that the precision of residual water level and tidal comparison parameters estimated by smoothed data is improved and semi-parametric model is useful for pre-processing of tidal data.关键词
