Efficiency of Nonparametric Estimators for Missing Observations of Bilinear Time Series with Gaussian Innovation
Abstract
A time series is defined as data recorded sequentially over a specified period.
Since the data are records taken overtime, missing observations in time series are very common. They may occur as a result of
lost records, deletion of outliers, calender effects and defective measuring instruments
Being unable to account for missing data has several limitations:
A severe miss-representation of the phenomenon under study
