ABSTRACT

The research discusses a completing model by using the measured data on the sea surface from 1996 to 2007 at Taipei port. The properties of the measured data are monthly mean and monthly standard deviation of all. By using the two properties, we can simulate the lost properties of both monthly mean and monthly standard deviation. The deseasoned data that were used to simulate lost wave data by using ARMA model. The simulated data were inserted into the lost section. In this model, we check the some properties of the both measured wave data and simulated wave data. The properties are ACF, PACF and spectrum. The properties of the two measured wave data and simulated wave data are the same. The completed data can represent the measured data. Propositions to stimulate future research about completing data are offered.
